Dial-Up Networking is used to connect to an Internet service provider (ISP) or other online service over a phone line or ISDN line. Windows NT Dial-Up Networking clients support the PPP protocol and the SLIP protocol. Most ISPs use these protocols, which enables Windows NT Workstation clients to connect to virtually all ISPs. Some ISPs support the Point-to-Point Tunneling Protocol (PPTP) and X.25 WAN protocols.
To connect to an ISP and use the Internet, you must configure Dial-Up Networking on your computer. Windows NT Dial-Up Networking steps you through the procedures to connect to the Internet.
To install Dial-Up Networking, double-click Dial-Up Networking in My Computer. Follow the instructions on-screen to complete Dial-Up Networking installation. For detailed instructions on installing Dial-Up Networking, see online Help.
To call an Internet service provider, you must create an entry in Dial-Up Networking. The Windows NT Dial-Up Networking wizard steps you through creating the first entry. This section explains how to manually configure a Dial-Up Networking entry to work with an ISP.
Double-click Dial-Up Networking in My Computer; or, click Start, point to Programs, point to Accessories, then click Dial-Up Networking. The first time Dial-Up Networking is started, the Dial-Up Networking wizard steps you through creating the first entry; otherwise, click New. Provide all the information requested by the Dial-Up Networking wizard. See the sections below for additional information about Internet configuration.
An Internet service provider must provide either PPP connections or SLIP connections to operate with Windows NT Dial-Up Networking.
1. Double-click Dial-Up Networking. Select a Phonebook entry to dial. Click More and select Edit entry and modem properties.
2. On the Server tab, in the Dial-up server type box, select PPP.
3. The TCP/IP and NetBEUI check boxes are automatically selected. Clear the IPX check box if it is selected. The Enable PPP LCP extensions (RFC 1570) check box enables newer PPP features and should be cleared only if you are unable to establish a connection while this setting is enabled. The Enable software compression check box should be selected.
4. Click TCP/IP Settings.
5. If your Internet service provider has assigned an IP address for your use, enter that number in the Specify an IP address box. If no number was assigned or if you know the server assigns IP addresses, select the Server assigned IP address check box.
6. If your Internet service provider has assigned primary and secondary DNS and/or WINS server IP addresses for your use, enter those numbers in the Specify name server addresses box. If no numbers were assigned or if you know the server assigns name server addresses, select the Server assigned name server addresses check box.
7. Leave the Use default gateway on remote network and Use IP header compression boxes selected.

Depending on your Internet service provider, you might need to make some modifications to your security settings, as described in the next section.
When you connect to the Internet service provider, some form of logon or authentication occurs. Your Internet service provider should tell you the logon sequence for its servers. You use the Script tab to configure Dial-Up Networking for logging on to the Internet service provider.
1. Click the Dial-Up Networking icon. Select a Phonebook entry to dial. Click More and select Edit entry and modem properties.
2. On the Security tab, select the authentication method specified by your Internet service provider.
Many Internet service providers require a clear-text terminal logon. If in doubt, select the Accept any authentication including clear text check box.
If you select Accept any authentication including clear text, you must also know the sequence of logon for your ISP, and any required commands.
3. If your Internet service provider has a well-defined logon sequence, you can create a script in the Switch.inf file that provides the required commands automatically at logon. You create and activate a script on the Script tab.
4. After you have selected the security and script settings, click OK. Click OK again to complete security configurations.
