Win95/98/NT Dialup, Authentication, Browsing Using TCPIP, IPX/SPX, or NetBEUI
This article has been written to help clarify how Windows NT clients, such as Windows 95, Windows 98, and Windows NT Workstation/Windows NT Server are supposed to be configured in order to successfully dial into a Windows NT network. The functionality of the clients includes dial-up authentication, domain authentication, gaining access to resources, and browsing.

This article can also be viewed as a Microsoft PowerPoint presentation and Webcast at the following location:

Review of Networking Objectives
The most common goal for dial-up networking is to be able to provide the following:
 * RAS validation
 * Windows NT domain logon (running scripts)
 * Gain access to network resources
 * Browse network resources

It is possible that one or more of these steps work, while others do not. To successfully achieve all of the above, look at both the client configuration and the server configuration. But first, a review of the components involved in Dial-up Networking (DUN).

Review of Dial-up Components
The following diagram displays the different DUN components and how they are generally attached to a network.

Configuration of Clients and Servers (General)
It is important to make sure that each client that dials into a RAS/RRAS server is properly configured. It is also important that the RAS/RRAS servers are properly configured. The following general configurations are recommended for the DUN client, as well as the RAS/RRAS server. These recommendations are not protocol specific and would apply regardless of the protocol being used for DUN. The next few sections deal exclusively with the general configuration of these components.

You may notice in looking at the configurations for each client that there is a great deal of overlap. This is intentional to show that the client operating systems are configured in much the same way as each other. The overlap could have been taken out, but has been left in so that a checklist could be taken straight from this article for each client during troubleshooting or installation.
 * Configuration of Clients (General)
 * Windows 95 Configuration (General)
 * Windows 98 Configuration (General)
 * Windows NT Configuration (General)
 * Configuration of Servers (General)
 * RAS Server Configuration (General)
 * RRAS Server Configuration (General)

Windows 95 Configuration (General)

 * Hardware Profiles - Either create a no-network hardware profile or verify that no network adapters have an IP address on the same network that you are trying to connect to. If the client normally uses DHCP to get an IP address, run "winipcfg" at an MS-DOS command prompt, and then click "release all" if dialing into the same network as the DHCP server.
 * Network Configuration - Verify that "Client for Microsoft Networks" is installed and selected under "Primary Network Logon". Press Esc at the first logon screen when starting the client to prevent network logon or a Windows-validated session. This allows domain logon through DUN.
 * Identification - The computer name must be unique and Workgroup name should be the same as the domain to which you are trying to connect.
 * Client for Microsoft Networks - Click "Log on to Windows NT domain", and then type the correct domain name in the "Windows NT domain" box.
 * Bindings - Make sure the protocol you are planning on dialing in with is selected. If the protocol you want to dial in with is not listed, you need to re-add that protocol, even if it already exists so that the bindings are regenerated.

Windows 98 Configuration (General)

 * Hardware Profiles - Either create a no-network hardware profile or verify that no network adapters have an IP address on the same network that you are trying to connect to. If the client normally uses DHCP to get an IP address, run "winipcfg" at an MS-DOS command prompt, and then click "release all" if dialing into the same network as the DHCP server.
 * Network Configuration - Verify that "Client for Microsoft Networks" is installed and selected under "Primary Network Logon". Press Esc at the first logon screen when starting the client to prevent network logon or a Windows-validated session. This allows domain logon through DUN.
 * Identification - The computer name must be unique and Workgroup name should be the same as the domain to which you are trying to connect.
 * Client for Microsoft Networks - Click "Log on to Windows NT domain", and then type the correct domain name in the "Windows NT domain" box.
 * Bindings - Make sure the protocol you are planning on dialing in with is selected. If the protocol you want to dial in with is not listed, you need to re-add that protocol, even if it already exists so that the bindings are regenerated.

Windows NT Configuration (General)

 * Hardware Profiles - Either create a no-network hardware profile or verify that no network adapters have an IP address on the same network that you are trying to connect to. If the client normally uses DHCP to get an IP address, run "ipconfig /release" from an MS-DOS command prompt. This is only necessary if the IP address you have is on the same network as the DHCP server.
 * Identification - The Windows NT client must be in its own workgroup initially, unless its already a member of the domain and has a machine account.
 * Services - Make sure that the Remote Access Service is installed. To configure this service:


 * Click the Start button, point to Settings, click Control Panel, and then double-click Network.
 * Add the Remote Access Service, click Properties, and then click Configure. For a dial-up client, select the "dial out only" option.
 * Also in RAS Properties, click Network, and then select the dial out protocols to be used.
 * Protocols - Make sure the protocol you want to use is installed.
 * Bindings - Make sure the protocol you are planning on dialing out with is available "bound" under Remote Access Server Service.
 * Dial-Up Networking


 * Runs a wizard initially for telephone prefixes.
 * On the Basic tab, type the name of the connection, and then type phone number to dial.
 * On the Server tab, select the protocol you want to use and leave all of the other options at their default settings.

Initial Setup Process
 * After you verify the above, you are ready to start the process of setting up a Windows NT client for logging on to a domain over a DUN connection.
 * After you create the DUN connection with the protocol of your choice, select the connection and dial it. You are then prompted for information, a name, password, and a domain.
 * After you are authenticated, go to your Network properties (click the Start button, point to Settings, click Control Panel, and then double-click Network), and on the Identification tab, click Change, and then join the domain you just dialed. You only need to join the domain once.
 * After you have successfully joined the domain, restart the Windows NT client.
 * After the client has restarted, you see the standard logon screen. Press Ctrl+Alt+Del as usual to log on. Make sure to select the "Log on using Dial-up Networking" checkbox.
 * The DUN connection box then appears so you can dial whichever DUN connection you want with any protocol you wish. These DUN connections must have already been created in order to be used for logon purposes. After you are connected, you are logged on and authenticated as if you were connected on the network LAN. More specific information about how to configure DUN connections with Windows NT appear later in this article.

RAS Server Configuration (General)
Please verify the following services and devices are configured on the RAS server:
 * Click the Start button, point to Settings, click Control Panel, and then double-click Network.
 * Click the Services tab, click RAS, and then click Properties. Make sure there is at least one RAS-capable device installed.
 * In the Network section of the RAS properties, make sure that for "Server Settings," you have selected each protocol your Dial-Up clients will be using to dial into this server.
 * In the Configure section of the RAS properties, make sure that you have selected "Receive calls only" or "Dial out and Receive calls" for a RAS server.

RRAS Server Configuration (General)

 * Click the Start button, point to Settings, click Control Panel, and then double-click Network.
 * Click the Services tab, and then click Properties. Make sure there is at least one RAS-capable device installed.
 * In the Network section of the RRAS properties, make sure that for "Server Settings", you have selected each protocol your Dial-Up clients will be using to dial into this server.
 * In the Configure section of the RRAS properties, make sure that you have selected "Receive calls as a RAS server" or "Dial out and receive calls as a demand dial router."

Configuration of Clients and Servers (Protocol Specific)
The following is a breakdown of each client and server configuration based on each of the protocols supported with the Microsoft Windows operating systems: NetBEUI, NWLink, and TCP/IP.

IMPORTANT NOTE: This portion of the reference should only be consulted after the general configuration options above have been verified and are configured correctly. Attempting to come directly to this section could lead to confusion, as the general steps of the configuration are assumed at this point.

Windows 95 Configuration (TCP/IP)

 * In the properties of the connectoid, click Server Types Advanced options, select Log on to Network Allowed network protocols, select TCP/IP Settings, and then leave the other default settings as they are.

Windows 98 Configuration (TCP/IP)

 * In the properties of the connectoid, click Server Types Advanced options, select Log on to Network Allowed network protocols, click TCP/IP Settings, and then leave the other default settings as they are.

Windows NT Configuration (TCP/IP)

 * After Windows NT starts up, press Ctrl+Alt+Del like normal to log on. Type you user name, password, and domain for authentication and make sure to select the Log on using Dial-up Networking checkbox.
 * Windows NT displays the Dial-up networking component and gives you the opportunity to choose which Dial-up connection you want. Choose a dial-up connection that is bound to TCP/IP.
 * For Dial-up TCP/IP Settings, leave the defaults.
 * If the RAS server is able to authenticate your RAS session, your domain logon proceeds as if you were connected through a local LAN connection.

RAS Server Configuration (TCP/IP)

 * Allow clients access to entire network.
 * Configure either a RAS pool or use DHCP.
 * If you use a RAS pool, make sure the RAS pool of addresses is on the same network as your LAN card (the pool must be in a range of first-bound IP address on any network adapter on the server.)
 * Install a WINS server, point to a WINS server, or let DHCP assign a WINS server to the clients, unless you are relying on clients to have lmhosts files.

RRAS Server Configuration (TCP/IP)

 * Allow clients to gain access to the entire network.
 * Configure either a RRAS pool or use DHCP.
 * If a RRAS pool, make sure the RAS pool of addresses is on the same network as your LAN card. Also, make sure to use the correct mask for the range of IP addresses you are creating for your dialup clients (the pool must be in a range of first-bound IP addresses on any network adapter on the server.)
 * Install a WINS server, point to a WINS server, or let DHCP assign a WINS server to the clients, unless you are relying on clients to have lmhosts files.

All Clients - Windows 95/98 and Windows NT
When you are using WINS on a network:
 * Right-click Dial-Up Adapter, click Properties, and then click the WINS configuration tab. Make sure that the "Use DHCP for WINS Resolution" checkbox is selected.

If not you are using WINS in your network, use an lmhosts file with the following entries (xxx.xxx.xxx.xxx represents the IP address of your PDC): <pre class="fixed_text">  xxx.xxx.xxx.xxx  WINPDC   #PRE  #DOM:DOMAIN-TEST xxx.xxx.xxx.xxx "DOMAIN-TEST    \0x1B"  #PRE
 * The first entry is the name of the PDC.
 * The second entry is for domain browsing, and should be entered with a total of 15 characters up to the "\" backslash.
 * The Lmhosts file must point to first-bound IP addresses on the network adapter of the PDC because NetBIOS only binds to the first IP of a network adapter.

Common Error Messages

 * Error 629: You have been disconnected from the computer you dialed. Double-click the connection to try again.
 * Error 633: The port is in use or not configured for Remote Access Dial-Out.
 * Error 720: No PPP control protocols configured.
 * Error Box: "You have been disconnected from the computer you dialed. Double-click the connection to try again."
