Setting up Dial-Up Networking in Windows NT 4.0

In version 4.0 of Windows NT, what used to be called Remote Access Services (RAS) is now called Dial-Up Networking (DUN), as it is in Windows 95. Follow these instructions to set up the Dial-Up Networking properly to connect to the Midtown system. If DUN is not installed, when you try to run it as shown below you’ll be sent into an installation routine and the necessary files will be copied from your Windows NT CD-ROM.

After DUN is installed, click Start, Programs, then Accessories and Dial-Up Networking. The first time DUN is used, it will go into a connection wizard and prompt for the setup information.

The first dialog box will say that the phonebook is empty, and to press okay to add an entry. Click the okay button.

Enter a name for this entry, typically "Midtown" or "Midtown Network". Continue to the next screen.

Check the first two boxes, I am calling the Internet and Send my plain text password. Do NOT check the third box. When you connect to the Midtown system, you will NOT want to be prompted for a username and password; it is automatic, using Password Authentication Protocol (PAP).

On the next screen, check the Use telephony dialing properties before entering our access phone number. This will let you control things like the modem speaker volume from the Telephony applet in the Control Panel. Type in our access phone number and our area code. Don’t enter an alternate phone number (there are none). Click Next to finish the connection wizard.

The next screen will show the phonebook entry you just created. Click Dial to connect. A Connect-To Midtown dialog box will appear. Enter your username (your logon name), and your password. If anything is showing in the Domain field, remove it! This is important. It may be showing "MIDTOWN" as the domain, which will make the logon name include MIDTOWN as part of the automatic logon. You’ll be logging on as "MIDTOWN/username" which will fail.

If you want to have the password saved, click Save Password. If you do save the password, the Connect-To box will not display the next time you connect. If you need to correct the connect-to information, see below to remove the saved password. Until you are sure the connection is working, it’s a good idea to not save the password.

That’s it. If everything goes as it should, you’ll see a box showing that your username and password is being verified, then another when you have successfully connected to the network. Minimize the connection box and start your application programs.

Leave everything blank; X25 is not applicable in this type of connection.


Linking Application Programs to the Dial-Up Networking

Application programs such as Internet Explorer and Netscape will have a way to set them to "use modem for the connection" or "use LAN for the connection". By choosing to use your modem, you’ll link them to the DUN. When they start and see they need to be connected to the Internet to continue, the DUN will automatically start.

This way you don’t need to go through the Start, Programs, and Accessories, then DUN to make the connection to the Internet. You may still want to, though. For example, if you plan on running a few different applications, make the connection first since closing one application will make the Internet connection hang up, perhaps before you have the chance to start the next application.
