I have a user who uses DUN on a Windows 2000 Pro workstation to connect to a government agency. When they use DUN to connect thier network mapped drives are disconnected. When they disconnect from DUN the networked mapped drives are available again.Is this a "feature" of Windows 2000 Pro or a bug? I have scoured the Microsoft web site and have found no info on this.

I think that your user is having a conflict with the Client for MS Networks option that is enabled on all DUN connections by default.
They dial up and connect, and then all of their name authentication requests go over the phone line instead of staying on your LAN.
Try this: go to the Properties of the DUN connection (in Network and Dial-up Connections). Click on the Networking tab.
Uncheck Client for Microsoft Networks (and make sure File and Printer Sharing is also unchecked).
Have the user then try to dial up and see if their mapped drives on your network stay on.

Now, doing this might cause other problems for the user connecting to the dial-up network, but one problem at a time!

hope this helps

Thank you for the Info. Unfortunately it did not help. I uncheck the Microsoft Client, but when I dial out it gets reset to checked and the LAN mapped drives become unavailable.
