Hope the following helps:

1. From ControlPanel/Networks/Add Software..., add "TCP/IP and related
   components," "Remote Access Service (RAS)," and "NetBIOS
   Interface."

   When these are added, other components will automatically be added 
   as well.

2. When RAS is added, you will be given the opportunity to configure
   it. NT will tell you that as you have no network adapter
   installed, it is disabling automatic restoration of network
   connections at startup, tell it OK. The RAS configuration dialog 
   box will come up, and list your modem as your only network device. 
   You will note that 'Disable automatic restoration, etc. is 
   checked (if not, select it). Don't worry about configuring the 
   modem at this point. NT gives you a 'Configure' button, but it 
   doesn't do anything. Press the "Network" button, and you will see
   three buttons under the heading Dialout protocols. NetBEUI and 
   TCP/IP are each selected. Deselect NetBEUI, and leave TCP/IP
   selected. Press OK/OK, and let NT do its thing and return you to
   the Network dialog box.

3. At this stage, confirm the following network components are
   installed: NetBIOS Interface, Remote Access Services, Simple TCP/IP
   Services SNMP Service, and TCP/IP protocol (note that SNMP and the
   Simple TCP/IP services should be installed while installing TCP/IP.
   Press OK.

4. After installing the network software, NT will configure bindings, 
   etc., and have you restart. Do so.

5. Go to ControlPanel/Services and set Remote Access Connection
   Manager startup to manual. Set Simple TCP/IP Services startup
   to automatic. Close Control Panel.

6. Execute the Remote Access Manager app.

7. Select ADD, and enter your ISP Name and phone number. 

   A. For the present, do not select Authenticate using current
      user name and password.

8. Confirm that your appropriate Port and Modem are shown. From
   the line of buttons on the bottom of the dialog box, select
   Modem. Set the initial spped, and enable hardware flow control
   and modem error control. Press OK.

9. Press the Network button. Select PPP and TCP/IP as the protocol.
   Enable Request LCP connections. Press the TCP/IP Settings... 
   button to bring up the TCP/IP dialog box.

10 Select Server Assigned IP Address. Select Use specific name server 
   address, and fill in the primary and backup DNS addresses. Leave
   the WINS and WINS backup addresses at 0. Select Use VJ Header
   compression, and Use default gateway on remote network. Press
   OK/OK. 

11 Press the Security button to bring up the Security Settings
   dialog box. Select Use clear text Terminal logon only. For 
   Terminal or Script, set before and after to none. Press OK/OK.

12 Highlight your ISP's phone number, and press the Dial button.
   After the connect, the RAS Terminal window opens, and you should be
   prompted by your ISP to logon:. Enter whatever you are supposed
   to at this time. Next comes password:, which you should enter.
   Next you will see a series of interesting characters. When they 
   start to appear, press the Done button. A message box will come
   up and inform you "verifying username and password." Then it will
   say logging your computer onto network. When the dialog box
   disappears, you are successfully logged on, and you may switch to
   your third-party net app.

11 Now you have confirmed that RAS works, so press RAS's Hang Up 
   button.

12 Create a RAS script by editing Switch.Inf in \System32\RAS. It's
   pretty easy (you can probably use the generic script with your
   username and password inserted). 

13 Go back to RAS and press the Edit button to alter the entry for 
   your ISP. Select Authenticate using current username and password.
   Press the Security button. Select Accept any authentication 
   including clear text. Under Terminal or Script, After Dialing, 
   select the entry that corresponds to the script you added for your
   ISP. Select OK/OK.

14 Dial up your ISP. You won't get the terminal window this time,
   you'll get the connection dialog box telling you (for a long time)
   it is verifying username and password, then connecting your 
   computer. When it has finished, start your third-party app, and
   enjoy.

15 If for some reason it doesn't work, well, that's why you're a
   member of this forum, no?
