Error: There is no dial tone
680

A phone line may be incorrectly connected to your modem or disconnected from your modem. The number may require a prefix, such as 9, to access external lines, or the number may be too long.

Make sure that the phone line is plugged into the correct socket in the modem. Also, make sure you added any special access numbers, such as the prefix 9 followed by a comma, to connect to an outside line (for example: 9,555-0100). For more information, see To configure phone number modifiers.

Check that there is no stutter tone, which indicates voicemail messages, on your phone line.

Many modems cannot dial more than 34 digits. When longer numbers are encountered, these modems split them into two or more parts, of which only the first part is dialed. This occurs with USRobotics and Multitech modems. The only known solution for this problem is to use another brand of modem.

For more information, see Microsoft Product Support Services.


Error: General error reported by device

Error: Access denied because user name and/or password is invalid on the domain
691

Either your user account is not registered with the domain listed, your password is expired, or you mistyped the information. If you do not specify a domain, the remote access server attempts to verify your user name and password on the domain of which it is a member.

Carefully retype your user name, password, and domain. If you are unsure of this information, contact your system administrator.


Error: Hardware failure in port or attached device
692

Your modem (or other device) is not responding because of the following:

The modem is turned off, malfunctioning, or is not securely connected to your computer.

To resolve this problem, do the following:

Reset your modem. For more information, consult your modem documentation.

If you are using an external modem, ensure that you are using a proper serial cable and that it is connected securely. You may want to try replacing the modem cable. Also, if you are using an adapter to connect your external modem to your serial port, ensure that the adapter is wired properly for modem communication. For example, a 9-to-25 pin adapter for a mouse does not work properly with a serial network connection.

Test the serial port or multiport adapter, and replace it if necessary.

Ensure that the handshaking options for the modem are configured properly. Consult your modem documentation for information about different handshaking options available for your modem.

If your modem is not supported by Network Connections, switch to a supported modem.

Verify that another application, such as HyperTerminal, is not using the communications port. If the port is being used, subsequently starting Network Connections may cause this message to appear.

Provides a space for you to type the starting address for the multicast IP group.


Provides a space for you to type the ending address for the multicast IP group.


Lists the available ATM addresses supported for ATM ARP/MARS service. When ATM address resolution requests are sent to these listed ATM network addresses, this computer will respond and provide resolution of IP addresses to ATM addresses for the requesting devices.

Address resolution is provided by the ATM ARP/MARS service to support TCP/IP connectivity for ATM network hosts that are active on the same logical IP subnet (LIS) as this computer. ATM ARP service supports classical IP-over-ATM connection [RFC 1577]. MARS supports multicast IP-over-ATM connection [RFC 2022].


Click to add a new ATM ARP/MARS server address to the list.


Click to edit a selected ATM ARP/MARS server address in the list.


Click to remove a selected ATM ARP/MARS server address from the list.


Lists the available IP address pairs for which broadcast and multicast forwarding is provided by ATM ARP/MARS. When IP address pairs are entered in the list, this computer forwards multicast and broadcast traffic sent to these addresses. This list contains paired IP addresses (a starting IP address and an ending IP address) and not ATM addresses.

If the list is empty, ATM ARP/MARS defaults to non-hubbed mode operation, in which it does not perform any forwarding for multicast group clients. Instead, ATM ARP/MARS returns a dynamic listing of ATM hosts currently registered for the multicast group address to requesting clients. Clients then establish separate point-to-point virtual connections with each of the group members to perform the actual multicasting.

If the list is not empty, ATM ARP/MARS uses hubbed mode operation. In this mode, the service provides its own ATM addresses to requesting clients in the form of a multicast server (MCS) list. When clients are provided with this list, ATM ARP/MARS on this computer is used as the MCS for forwarding multicast and broadcast traffic to the specified IP address range. ATM ARP/MARS then establishes point-to-multipoint virtual connections for requesting group members for multicasting.

Provides a space for you to type in a descriptive name for this permanent virtual circuit (PVC). This name is used only for display purposes to identify each configured PVC.


Provides a space for you to type a number between 0 and 255 for the virtual path identifier (VPI) to be used by this permanent virtual circuit (PVC). Virtual paths are a way to logically divide ATM network bandwidth at each piece of network hardware.

ATM hardware devices define a virtual path and allocate to it a fixed amount of bandwidth. Bandwidth is then further allocated from within each path for use as virtual channels. The path identifiers that you type here are used in combination with the virtual channel identifier (VCI) specified in Virtual Circuit to identify the exact physical transmission path link between ATM hardware on this computer and its next physical point of connection with a remote hardware device port, such as an ATM switch.


Provides a space for you to type a number between 32 and 1023 for the virtual channel identifier (VCI) to be used by this permanent virtual circuit (PVC).

The channel identifiers that you configure here identify a specific transmission channel within the virtual path specified in Virtual path ID. The combination of the VPI and VCI fully identify the transmission path taken by this virtual circuit. VPI/VCIs only need to be unique for each physical transmission path, not for the entire network.

VCIs between 0 and 32 are reserved identifiers used for standard operations such as signaling, maintenance, and resource management.


Provides a space for you to select the ATM adaptation layer (AAL) type which is used for adapting units of data from higher layer protocol communications into cells, which are used for ATM layer communications.

Currently, only ATM Adaptation Layer 5 (AAL5) is supported for use with ATM services. AAL5 performs most effectively for adapting LAN traffic and is widely implemented today in most ATM hardware products.


 Provides a place for you to select the type of ATM application for which this permanent virtual circuit (PVC) is used. Choose from any of the following four supported types:

•	ATM ARP Select if this PVC supports ATM ARP client use. You must choose this application type if you select PVC only in the Advanced TCP/IP Settings for the ATM ARP client.

•	PPP/ATM Client Select if this PVC supports a permanent PPP-type Network Connections connection from this computer. In this role, the PVC is used only when outbound calls, made by applications on this computer that use Network Connections, match the address specified in Match only to applications calling this address.

•	PPP/ATM Server Select if this PVC supports a permanent PPP-type Routing and Remote Access service dial-up service on this computer for dial-up clients. In this role, the PVC is used by inbound PPP/ATM calls answered by this computer that match the preconfigured well-known addresses displayed in Match only to applications answering this address.

•	Custom Select if the PVC is needed to support customized matching criteria that you specify in the Advanced properties dialog box. When Custom is selected, this computer uses this PVC only when outbound calls (call matching) or inbound calls (answer matching) match settings that you have configured.

If you select predefined application types (other than Custom), you can only specify additional Quality of Service (QoS) parameters for use as call/answer matching criteria in Advanced properties. Where QoS criteria are specified, only calls made or answered that match the QoS parameters that you specify in Advanced properties are allowed to use this PVC.

Provides a space for you to type a peak cell rate for ATM traffic sent by this computer over this PVC. This is the maximum rate of transfer allowed for any traffic sent using this PVC.


Provides a space for you to type a sustained cell rate for ATM traffic sent by this computer over this PVC. This is the average rate of transfer required for any traffic sent using this PVC. This rate is computed based on measurements taken over an extended period of time.


Provides a space for you to type a maximum burst size (MBS) for ATM traffic sent by this computer using this PVC. This is the maximum number of bytes allowed to be sent during a single burst of data before changing to a lower rate of transmission. A burst may occur when the Peak transmit rate or peak cell rate is in effect.


Provides a space to type the maximum protocol data unit (PDU) size that can be adapted from upper layer protocols (such as IP) for any ATM traffic sent by this computer using this PVC.


Provides a space for you to select the ATM Quality of Service (QoS) category for ATM traffic sent by this computer using this PVC.

Available Bit Rate Connections not requiring a guaranteed rate of transfer, such as file transfer and e-mail. ABR uses feedback from the network to control the data rate for the PVC. ABR requires UNI 4.0 signaling support.

Constant Bit Rate Connections requiring a guaranteed continuous rate of transfer, such as real-time voice or video.

Unspecified Bit Rate Connections requiring route establishment but not guaranteed delivery, such as batch file transfer and lower priority bulk e-mail.

Variable Bit Rate Connections with variable time delay requirements with burst traffic that require a minimum cell loss ratio.

Windows ATM services provide the mechanisms to request connections using all of these service categories. Whether PVCs can be created using a particular service category is also dependent upon the capabilities of the rest of the ATM network infrastructure. This includes support of the selected service category by the ATM adapters, drivers, and switches. Nearly all equipment supports both UBR and CBR.

Specifies whether the computer attempts authentication to the network as a guest when user or computer information is not available.


Specifies whether the computer attempts authentication to the network when a user is not logged on.


Lists the types of ISDN lines you can select. The choices are listed in order from the highest (64 Kbps digital) to the lowest (56 Kbps voice) quality line type.


Specifies whether to start negotiation with the selected line type and then negotiate with a lower quality line type, depending on the condition of the line.

Some ISDN cards negotiate both the line type and the number of channels if the Negotiate line type check box is selected. In other words, not only does the card start negotiating at the highest quality line type (64 Kbps digital) and fall back to the lowest quality (56 Kbps voice), but in many cases the card also falls back from multiple channels to fewer channels, if necessary.


Specifies whether to use proprietary protocols. If the server you are dialing in to supports only proprietary protocols, select this check box. For example, if you use DigiBoard devices on both the server and the client.

If you want to use Multilink over multiple ISDN lines, clear this check box. Multilink does not require proprietary protocols on the server or the client.


Specifies whether to compress data before transmitting it. If you select this check box, turn off software compression.

Not all ISDN cards offer hardware compression. If you select this check box and your card does not offer compression, the data throughput will not improve. If you do not know whether your card has compression, check with the manufacturer of the card.


Provides a space for you to type a new channel setting. You can also click the arrows to select the number of channels to use. If your card allows you to aggregate more than one ISDN channel, and the ISDN card for the remote access server is configured to allow channel aggregation, you can improve throughput by using multiple channel selection. See To make a dial-up connection by using an ISDN line in Help.

Not all ISDN drivers allow you to restrict channel aggregation. If you have a nonrestricting driver and your computer is configured to receive calls, ask clients that are dialing in to specify only one or two channels. Otherwise, one user with several ISDN cards might monopolize all channels on the server.

You cannot connect through more channels than the number available on the ISDN card. In fact, selecting more channels than the maximum number available may prevent you from connecting.


Lists the available modem speeds that your modem can use to negotiate with the modem on the remote access server. The speed, in bits per second (bps), may decrease during negotiation.


Depending on the modem that is installed, lists the protocols that are available for use. Examples of protocols are Use error control, Standard error correction, and Error control forced.


Specifies whether to enable hardware handshaking. With this feature, the modem tells the remote access software when the line is congested or clear, so that the remote access software temporarily stops transmitting data when necessary. This handshaking streamlines data transmission, prevents overrun errors, and thus improves overall data throughput.


Specifies whether to check errors on blocks of data through cyclical redundancy checks (CRCs). Modem error control causes the modem to retransmit garbled data, ensuring that only error-free data passes through the modem.


Specifies whether to compress the modem-to-modem data stream. This reduces the number of bytes transmitted and therefore reduces the transmission time. The reduction achieved depends on the amount of redundancy in the transmitted data.

Software compression is more effective than hardware compression because a much larger pattern buffer is available on the computer than on the modem. In addition, modem compression delays the first transmission while the pattern buffer of the modem is filled at computer-to-modem speed. Software compression accomplishes this task at the much faster memory speed and transmits compressed data over the entire computer-to-computer link rather than just the modem-to-modem segment.

In general, you should not enable modem compression and software compression at the same time because no benefit is gained from compressing precompressed data. In fact, the size of the transmitted data may actually increase, depending on the algorithm that is used by the modem.


Specifies whether a script is run before dialing. You can use scripts to automate logging on to a remote network.


Lists the available scripts to use before dialing.

See Automating the dial-up logon process by using Windows scripting or Automating the dial-up logon process by using Switch.inf scripts in Help.

If you clear the check box, LCP cannot send Time-Remaining and Identification packets and request callback during the LCP negotiation of PPP.


Specifies whether software compression is enabled.

Network Connections offers software data compression in addition to support for modem compression. Therefore, you do not have to turn on modem compression to benefit from faster throughput.

For recommendations about getting the most out of compression, see Data compression in Help.


Specifies whether Multilink negotiation is enabled for a single link connection. If your remote access server supports this feature, you may notice improved audio quality. If you enable this option, you may not be able to connect to other remote access servers.


Lists the available devices that you can use for incoming connections. To enable the use of a device, click the check box next to the device name. To disable the use of a device, clear the check box next to the device name.


Specifies whether Multilink is enabled. Multilink combines multiple physical links into a logical bundle, which increases bandwidth for an incoming connection. On a computer running Windows XP Professional, Multilink is always enabled. On a computer running Windows 2000 Server, Multilink is enabled and is configurable if your incoming connection uses more than one device, line, or communications link.


Click to configure settings for the selected device.


Specifies whether virtual private network connections can be made to this computer.

See Virtual private network (VPN) connections in Help.


Specifies whether an incoming connection icon is displayed in the notification area of the taskbar when a connection is made.


Specifies whether a user account on this computer can make an incoming connection. If you enable access for incoming connections here, other factors may prevent a user from logging on. A user's account may be disabled or locked out in Local Users and Groups in Computer Management, or the user may attempt to connect outside of allowed hours.


Click to add one or more new users to the user list of the local computer.


Removes the selected user from the user list of the local computer.


Click to configure user settings such as user name, password, and callback privileges.

You can add or remove clients and services, but the TCP/IP, IPX/SPX, AppleTalk network protocols, and File and Printer Sharing for Microsoft Networks are the only network components that you can modify for an incoming connection. Any installed components other than these are always used by incoming connections; they cannot be disabled and display unavailable check boxes.


Click to add a client, service, or protocol to the list in Network components.


Removes a selected client, service, or protocol from the list in Network components.


Click to configure the selected client, service, or protocol for this computer.


Specifies whether users connecting to this computer can use resources on the network that this computer resides on.


Specifies that DHCP assigns IP addresses to users who are connecting to this computer. With DHCP, a network can assign a temporary IP address to a host automatically when the host connects to the network. If no DHCP server is available, the Automatic Private IP Addressing (APIPA) feature assigns a random IP address (169.254.xxx.xxx).


Specifies that IP addresses for incoming connection clients are assigned based on a predefined range of addresses rather than by a DHCP server. This range is derived from a starting address and an ending address. For more information about specifying the correct starting and ending addresses, see Incoming connections and IP addresses in Help.


Provides a space for you to type the starting address that, when used with the ending address, produces the range of addresses assigned to incoming connection clients. For more information about specifying the correct starting address, see Incoming connections and IP addresses in Help.


Provides a space for you to type the ending address that, when used with the starting address, produces the range of addresses assigned to incoming connection clients. For more information about specifying the correct ending address, see Incoming connections and IP addresses in Help.


Specifies whether the incoming user can provide an IP address. This option is useful if a predefined address is reserved for a particular incoming user. The potential for address conflict exists because the user may enter an address that already exists on the network.


Specifies that IPX network numbers are assigned automatically. The incoming connection uses the NetWare Router Information Protocol (RIP) to verify that a randomly assigned IPX number is not in use in the IPX network. If RIP verifies that the number is not in use, the connection assigns that number to the incoming user.


Specifies that IPX network numbers are assigned manually. This is useful if you want more control of network number assignments for security or monitoring purposes.


Specifies whether the same IPX network number is assigned to all computers that connect by using the IPX protocol.


Provides a space for you to type either the IPX network number that is assigned to all incoming users or an IPX network number that the computer begins assigning numbers from. The NetWare Router Information Protocol (RIP) verifies that IPX numbers are not in use in the IPX network, and the connection assigns those numbers to incoming users. If you specify IPX network numbers, there is a risk that you may configure a pool of numbers that is already in use on the network.


Specifies whether the dial-up computer can request a specific IPX network number, rather than using the node number that is provided by the incoming connection. If this check box is not selected, callers cannot request a specific node number.


Specifies whether users that connect to this computer can use resources on the network that this computer resides on.


Lists the local area device that is used to make the connection.


Click to configure the settings of the device in Connect using.


Specifies whether an icon is displayed in the notification area of the taskbar when a connection is made.

Specifies that the user can set the callback number. For information about the sequence of events that occur when you use callback, see Callback in Help.


Specifies that callback is never used.


Specifies whether to request identity authentication information before attempting to connect. This information can include a user name, a password, or a certificate (if you are using smart card authentication). If you are using an extra security device, such as a smart card, and the information is not needed by the security device, you are not requested to supply the information before you connect.


Specifies whether to request logon domain information before attempting to connect. This option is only available if you also prompt for user name, password, or certificate information. If you are using an extra security device, such as a smart card, and logon domain information is not needed by the security device, you are not requested to supply the logon domain before you connect.


Lists the available levels of data encryption that you can enforce. You can prohibit encryption, allow users to connect even if their data is not encrypted, or require encryption.


Specifies that Extensible Authentication Protocol (EAP) is used with this connection. EAP authenticates remote access users in conjunction with other security devices. These devices include smart cards and certificates.


Specifies that the selected authentication protocols are allowed.


Specifies whether to use the Password Authentication Protocol (PAP). PAP uses plaintext passwords and is the least sophisticated authentication protocol. PAP is typically used if your connection and the server cannot negotiate a more secure form of validation. You may need to use this protocol if you are calling a non-Microsoft server.


Specifies whether to use the Shiva Password Authentication Protocol (SPAP). By using SPAP, you can dial into and authenticate on a Shiva server. If your server requires you to use SPAP, you cannot select Require encryption (disconnect if server declines) in Data encryption.


Specifies whether to use the Challenge Handshake Authentication Protocol (CHAP). CHAP negotiates a secure form of encrypted authentication. Message Digest 5 (MD5), an industry standard, transforms data (for example, a password) in such a way that the result is unique and cannot be changed back to its original form. CHAP uses challenge-response with one-way MD5 hashing on the response. In this way, you can prove to the server that you know your password without actually sending the password over the network. By supporting CHAP, Network Connections is able to securely connect to almost all other PPP servers.


Specifies whether to use MS-CHAP. Microsoft created MS-CHAP to authenticate remote Windows workstations, providing the functionality to which LAN-based users are accustomed while integrating the encryption and hashing algorithms used on Windows networks. MS-CHAP uses a challenge-response mechanism with one-way encryption on the response.

Where possible, MS-CHAP is consistent with standard CHAP. Its response packet is in a format specifically designed for Windows-based networking products. In addition, MS-CHAP does not require the use of plaintext or reversibly encrypted passwords, and a system administrator can define authentication retry and password changing rules for the users that connect to your server.


Specifies whether to use an older version of MS-CHAP that is specific to Windows 95 servers. This is only required if your connection is to a server running Windows 95.


Specifies whether to use a new version of the Microsoft Challenge Handshake Authentication Protocol (MS-CHAP v2). This protocol provides mutual authentication, stronger initial data encryption keys, and different encryption keys for sending and receiving. To minimize the risk of password compromise during MS-CHAP exchanges, MS-CHAP v2 drops support for the MS-CHAP password change and does not transmit the encoded password.

For VPN connections, MS-CHAP v2 is offered before the legacy MS-CHAP. Updated Windows clients accept MS-CHAP v2 when it is offered. Dial-up connections are not affected.


Specifies whether to automatically provide your logon name, password, and domain (if available). This option is available if you are using MS-CHAP or MS-CHAP v2. By selecting this option, your logon process is streamlined as the same set of credentials are applied to your domain authentication and the remote access authentication processes.

Also, if you are prompted to change your password during remote access authentication, those changes are applied to your session, and you can immediately and transparently access your network resources under the new credentials. If you do not select this option, and you are prompted to change your password during remote access authentication, those remote access authentication changes are not applied to your session. In order to access remote resources, you must log off and on again.


Lists the Extensible Authentication Protocol (EAP) authentication types that are installed on your computer. If the EAP type that you need is not on the list, then it is another EAP type and you must install it. For more information, see your system administrator.


Click to configure the properties of the selected Extensible Authentication Protocol (EAP) authentication type.


Specifies that a predefined set of authentication methods and encryption requirements are negotiated with the server during a PPP exchange. If you select this option, you can view the settings by clicking Advanced (custom settings), and then clicking Settings.


Lists the available identity authentication settings that you can use. On a dial-up connection, these range from an unsecured password to smart card authentication. On a VPN connection, the authentication settings range from a required secured password to smart card authentication.


Specifies whether your logon name, password, and domain (if available) are used in the authentication process.


Specifies whether to require the use of data encryption. If you select this option, and data encryption is not used by the connecting server, the connection disconnects. If you do not select this option, encryption is attempted, but the connection is made even if encryption is not used. If you want to prevent encryption, click Advanced (custom settings), click Settings, and in Data encryption, click No encryption allowed (disconnect if server requires encryption).


Specifies that authentication methods and encryption requirements are individually enabled, configured, and disabled. This requires a knowledge of security protocols.

If you select this option, you can view the settings by clicking Advanced (custom settings), and then clicking Settings. If you click Advanced (custom settings), and then you click Typical (recommended settings), authentication and encryption settings are reset to their default values.


Click to individually enable, configure, and disable authentication methods and encryption requirements.

Click to search for a script file.

The scripting feature is supported for serial modems. It is not supported for ISDN devices.


Specifies whether to allow users to create and modify connections before attempting the Windows logon process. For example, a user in a remote location may need to quickly change the phone number for the dial-up connection. By selecting this option, the user does not need to present Windows logon credentials for the primary network before modifying the dial-up connection. This option allows users who are not logged on to make changes to your configuration.

If this check box is cleared, the settings configured here are used for all ATM virtual circuits made from this computer, including both switched virtual circuits (SVCs) and permanent virtual circuits (PVCs).

To configure a PVC on this computer, you can use the ATM PVC Configuration dialog box. To configure an SVC, in the Network Connections folder, double-click Make New Connection.


Specifies whether Van Jacobson (VJ) TCP/IP packet header compression is used. VJ compression is a protocol optimization widely supported in dial-up implementations. If disabled, an attempt is made to detect compressed packets and, if found, VJ compression mode starts automatically. This gives the best chance of a successful connection and, in most cases, the best performance available.

In some cases, where both ends are attempting to detect compression, compression might not be activated. If you are certain that the remote access server supports VJ compression, select this check box to activate compression and improve performance. You can verify that compression is occurring by monitoring the compression information on the General tab of the Status dialog box for the connection.

If this check box is selected and the remote access server does not support VJ compression, inbound traffic continues normally but outbound traffic does not succeed. Because most applications require communication in both directions, the session usually appears stopped.


Lists the frame size of outgoing Serial Line Internet Protocol (SLIP) frames. The default setting is 1006. You can also use 1500 if your remote access server accepts 1500-byte SLIP frames.


Lists the Internet Protocol security (IPSec) policies in place on this computer.

The local setting is used only if the associated Group Policy is disabled or unspecified.


Provides a space for you to type the Internet Protocol (IP) address for the DNS server.


Provides a space for you to type a domain suffix to add to your domain suffix search list.


Specifies that network addresses for DNS servers are automatically obtained from the network. If you select this option, a DHCP server or Point-to-Point Protocol (PPP) dial-up network access server provides this information. This option is not available for dial-up connections that call a Serial Line Internet Protocol (SLIP) server.


Provides a space for you to specify a DNS suffix for this connection. If a DHCP server configures this connection and you do not specify a DNS suffix, a DNS suffix for this connection is assigned to this connection by the appropriately configured DHCP server. If you specify a DNS suffix, the DNS suffix assigned by the DHCP server is ignored. The local setting is used only if the associated Group Policy is disabled or unspecified.


Specifies that network addresses for DNS servers used by this computer are manually specified. If you select this option, you must type the IP addresses for your DNS servers in Preferred DNS server and Alternate DNS server. If you are not sure which IP addresses to use, check with your network administrator or Internet service provider.


Specifies whether DNS dynamic update is used to register the IP addresses and the connection-specific domain name of this connection. The connection-specific DNS name of this connection is the concatenation of the computer name (which is the first label of the full computer name) and the DNS suffix of this connection. The full computer name is specified on the Computer Name tab (available in System in Control Panel). If the Register this connection's addresses in DNS check box is selected, this registration is in addition to the DNS registration of the full computer name. The local setting is used only if the associated Group Policy is disabled or unspecified.


Provides a space for you to type the IP address for the preferred or primary DNS server for this computer. This server is used first to resolve DNS names to IP addresses for DNS names queried by this computer that cannot be resolved by using local name resolution information (such as cached DNS names or names contained in a Hosts file).


Specifies that resolution for unqualified names that are used on this computer are limited to the domain suffixes of the primary suffix and all connection-specific suffixes. Connection-specific suffixes are configured in DNS suffix for this connection. The primary DNS suffix is configured by clicking Properties on the Computer Name tab (available in System in Control Panel). The local setting is used only if the associated Group Policy is disabled or unspecified.

For example, if your primary DNS suffix is dev.wcoast.microsoft.com and you type ping xyz at a command prompt, the computer queries for xyz.dev.wcoast.microsoft.com. If you also configure a connection-specific domain name on one of your connections for bldg23.dev.wcoast.microsoft.com, the computer queries for xyz.dev.wcoast.microsoft.com and xyz.bldg23.dev.wcoast.microsoft.com.


Specifies whether resolution for unqualified names used on this computer includes the parent suffixes of the primary DNS suffix up to the second-level domain. The primary DNS suffix is configured by clicking Properties on the Computer Name tab (available in System in Control Panel). The local setting is used only if the associated Group Policy is disabled or unspecified.

For example, if your primary DNS suffix is dev.wcoast.microsoft.com and you type ping xyz at a command prompt, the computer also queries for xyz.wcoast.microsoft.com and xyz.microsoft.com.


Provides a space for you to type the IP address for the alternate or secondary DNS server for this computer. This server is used if the DNS server specified in Preferred DNS server is unreachable or cannot resolve DNS names to IP addresses for DNS names queried by this computer.

Specifies that resolution for unqualified names that are used on this computer are limited to the domain suffixes listed in Append these DNS suffixes. When this option is selected, the primary and connection-specific DNS suffixes are not used for unqualified name resolution. The local setting is used only if the associated Group Policy is disabled or unspecified.

For example, if you add dev.microsoft.com and test.microsoft.com to the list of DNS suffixes and type ping xyz at a command prompt, this computer queries for xyz.dev.microsoft.com and xyz.test.microsoft.com.


Provides a space for you to type an ATM network address (a 20-byte number sequence in hexadecimal) for the switch or other ATM network device that provides resolution of logically assigned IP addresses to ATM physical network addresses.


Provides a space for you to type the size in bytes of the maximum transmission unit (MTU) that this computer uses during IP-over-ATM communication with other TCP/IP hosts.

The MTU value that you set here only affects IP-over-ATM communication from this computer with other hosts on TCP/IP networks. It does not affect the maximum transmission unit size of data sent on ATM networks, which is physically limited to 53 bytes (the required length of each individual ATM cell).


Provides a space for you to type the TCP port number, UDP port number, or IP protocol number for the traffic that you want to permit.


Specifies whether TCP/IP filtering is enabled for all adapters. TCP/IP filtering specifies the types of incoming traffic destined for this computer that are passed up to the TCP/IP protocol for processing. To configure TCP/IP filtering, select this check box and specify the types of allowed TCP/IP traffic for all adapters on this computer in terms of IP protocols, TCP ports, and UDP ports. ICMP traffic cannot be excluded.

If TCP/IP filtering is enabled, the configured filters might be too restrictive, and traffic needed for network processes might not be allowed. To determine whether TCP/IP filtering is preventing the passing of needed TCP/IP traffic, you can temporarily disable TCP/IP filtering, and then retry the process.

A default gateway is a local IP router that is used to forward packets to destinations beyond the local network. A Metric of Automatic specifies that the default route metric for the default gateway is automatically calculated based on the speed of the interface. The interface with the highest speed has the lowest default route metric.


Provides a space for you to type the IP address for the default gateway that you want to add. This is the address of a local IP router on the same network as this computer that is used to forward traffic to destinations beyond the local network. The value in each field must be a number from 0 through 255.

A gateway is a router that connects separate IP network segments. For example, a network segment might need a gateway to connect it to another network segment, a wide area network (WAN), or to the Internet.


Provides a space for you to type an Internet Protocol (IP) address obtained from your network administrator or Internet service provider. An IP address is a 32-bit number that is notated by using four numbers from 0 through 255, separated by periods.


Provides a space for you to type the interface metric for this network connection. The metric indicates the cost of using the routes in the routing table that are derived from the interface configuration and becomes the value in the Metric column for those routes in the IP routing table. If there are multiple closest matching routes to a destination in the IP routing table, the route with the lowest metric is used. The default value is 1. To view the IP routing table, type route print at a command prompt.

Specifies that this network connection does not use NetBIOS-over-TCP/IP (NetBT) and Windows Internet Name Service (WINS).

By default, this option is not selected to enable NetBIOS and WINS use on this computer. This setting is only used if this computer does not communicate by name with computers that use earlier versions of Windows that require WINS or legacy applications that require NetBT.

Before selecting this option, verify that you do not need to use WINS or legacy NetBT-type applications for this network connectionfor example, if you communicate only with other computers running this operating system (or Windows 2000) that use and register their names with DNS, or Internet computers using DNS-aware applications.


Specifies that this network connection uses NetBIOS-over-TCP/IP (NetBT) and Windows Internet Name Service (WINS).

When an IP address is manually configured, select this option to enable NetBIOS and WINS use on this computer. This setting is required if this computer communicates by name with computers that use earlier versions of Windows. Before changing this option, verify that you do not need to use NetBIOS names for this network connectionfor example, if you communicate only with other computers running this operating system (or Windows 2000) that use and register their names with DNS, or computers on the Internet that use DNS.

 This option is selected by default for dial-up connections.


Specifies that this network connection obtain the setting to enable or disable NetBIOS over TCP/IP (NetBT) from a Dynamic Host Configuration Protocol (DHCP) server. The enabling or disabling of NetBT through DHCP is provided with the value of the Disable NetBIOS over TCP/IP (NetBT) Microsoft vendor-specific DHCP option.

When an IP address is automatically obtained, this option is selected by default so that this computer uses the NetBT setting as optionally provided by the DHCP server when this computer obtains an IP address and configuration lease. If the Disable NetBIOS over TCP/IP (NetBT) DHCP option is provided by the DHCP server, the value of the option determines whether NetBT is enabled or disabled. If the Disable NetBIOS over TCP/IP (NetBT) DHCP option is not provided by the DHCP server, NetBT is enabled.

If you are manually configuring an IP address, selecting this option enables NetBT. This option is not available for dial-up connections.


Specifies whether, for the duration of the connection, the default gateway on the remote network is used. When a dial-up or virtual private networking connection is made, a new default route that uses the connection to the remote access server is added to the IP routing table and is assigned the lowest metric. If there is an existing default route, it remains in the routing table but is changed to a higher metric. By adding the new default route with the lower metric, locations reachable by using the original default route will no longer be reachable.

For example, a computer running this operating system (or Windows 2000) on a corporate network has a LAN connection on the corporate network and is configured with a default gateway of a local IP router. If the Use default gateway on remote network option is selected, when a user on that computer dials an Internet service provider (ISP) to access the Internet, the default gateway becomes the ISP, not the local corporate router. Therefore, all locations on the corporate network, except those on the local network, become unreachable for the duration of the connection to the ISP. If the Use default gateway on remote network option is cleared, then the original default route is unmodified, a new default route is not added, and locations on the Internet are not reachable.


Click to add a new WINS server to the list of servers that this network connection uses and contacts for assistance in servicing NetBIOS names that are used by this computer.

Removes the IP address for the selected WINS server in WINS addresses, in order of use.


Lists the WINS servers that TCP/IP queries to resolve NetBIOS names. WINS servers are queried in the order in which they are listed here.


Moves the selected WINS server up in the list in WINS addresses, in order of use.


Specifies that TCP/IP use Automatic Private IP Addressing (APIPA) if a Dynamic Host Configuration Protocol (DHCP) server is not found. APIPA assigns an IP address from the range 169.254.0.1 through 169.254.255.254 and a subnet mask of 255.255.0.0. APIPA does not assign a default gateway, Domain Name System (DNS) servers, or Windows Internet Name Service (WINS) servers.


Specifies that TCP/IP use the alternate configuration if a Dynamic Host Configuration Protocol (DHCP) server is not found. This alternate configuration is useful when the computer is used on more than one network, at least one of the networks does not have a DHCP server, and an Automatic Private IP Addressing (APIPA) configuration is not wanted. A good example is a laptop computer that is used at the office and at home. At the office, the laptop uses a DHCP-allocated TCP/IP configuration. At home, where there is no DHCP server present, the laptop automatically uses the alternate configuration, allowing easy access to home network devices and the Internet. This enables the laptop to operate seamlessly on both networks without manual TCP/IP reconfiguration.

Provides a space for you to type the alternate configuration subnet mask number obtained from your Internet service provider or network administrator. This number is combined with the IP address number to identify which network your computer is on.

A subnet mask is a 32-bit number that is notated by using four numbers from 0 through 255, separated by periods. Typically, default subnet mask numbers use either 0 or 255 as values (such as 255.255.255.0), but other number values can appear.


Provides a space for you to type the alternate configuration IP address for the default gateway. This is the address of a local IP router on the same network as this computer that is used to forward traffic to destinations beyond the local network. The value in each field must be a number from 0 through 255.

A gateway is the connection or interchange point that connects separate IP networks. For example, a local area network (LAN) might need a gateway to connect it to a wide area network (WAN) or to the Internet.


Provides a space for you to type the alternate configuration IP address for the preferred or primary DNS server for this computer. This server is used to resolve DNS names to IP addresses for DNS names queried by this computer that cannot be resolved by using local name resolution information (such as cached DNS names or names contained in a Hosts file). An IP address is notated by four numbers from 0 through 255, separated by periods.


Provides a space for you to type the alternate configuration IP address for the alternate or secondary DNS server for this computer. This server is used if the DNS server specified in Preferred DNS server is unreachable or cannot resolve DNS names to IP addresses for DNS names queried by this computer.
