When running the Microsoft Windows Connection Manager 1.2 on a Windows NT 4.0 computer, you should have at least Service Pack 3 installed. If you have trouble connecting with the Connection Manager, and the troubleshooting help file doesn't help you, Microsoft says you should uninstall Remote Access Services (RAS), reinstall it, and then reinstall the NT Service Pack. Also, you should double-check in RAS that your virtual private network, or VPN, is configured for "Dial-Out Only".
If your Novell NetWare 5 network server uses an Intel EtherExpress Pro 100 Intelligent Server Network Interface Card, users may not be able to connect to your network if NetWare 5 Support Pack 1 is installed.

As a fix, download 100VDISK.EXE 3.0 from Intel at http://support.intel.com/support/etherexpress/pro100/index.htm.
