Dial-Up Configuration

Configuring a stand alone Windows NT machine to connect to Seanet.

This document will walk you through the process of checking the settings for NT Workstation 4.0's Remote Access Service and Dial-Up Networking. The instructions in this document will also work with Windows NT Server 4.0. For those connecting Local Area Networks (LANs) to the Internet, please refer to our NT Routing Setup document.

Warning: Not following these instructions carefully will cost you lots of time and frustration!

In order to proceed, you will want to make sure that you are logged into the NT machine as Administrator, or a user with administrator privileges.

Remember that it is case-sensitive, so you will need to be careful while typing it in. Leave the Domain field blank. If you enter anything here, you will receive an invalid login. Save Password if you do not want to enter your password every time you log in to Seanet. Click OK. You should connect successfully! WinNT


Login Problems

  • Make sure that you are only entering your Seanet login name for the username and not your password or your real name. Also, make sure that you have nothing in the Domain field.
  • You may receive an invalid login at some point after you have saved your username and password. To fix this, you'll want to go to the main Dial Up Networking screen click on More, then Edit Entry and Modem Properties. Click on the Security tab and click Unsave Password. Click Ok.

Modem Problems

  • Try power cycling the modem. If it is external, simply turn it off and back on after a couple seconds, or unplug it and plug it back in. If the modem is internal, restart the computer.
  • If power cycling the modem doesn't do the trick, find out the brand name of the modem you're using, either from your manual or by going to Control Panel and Modems. Our technical support staff has a long list of modem initialization strings that may improve your connection. Give them a call and let them know the problem you're having and the brand name of the modem. They can help.
  • If you already have an initialization string and just need to know where it goes, go into My Computer, then Control Panel, and then Modems. Click on the Properties, the Connection tab, and then click on the Advanced button. In the Extra Settings field, type the initialization string. Click OK, then OK again, then Close. You will now want to restart the computer, or reset the modem if it's external.
