Duplicate name on network

I have an NT 4.0, service pack 5 machine that I added a new modem to and then set up the Remote Access service.  After doing this I rebooted the computer and the following services failed to start:  Workstation, Alerter, Computer Browser, Messenger, Net Logon, RPC Locator.

In Event Viewer, the Workstation service terminated with the following error:  A duplicate name exists on the network.  The other services probably failed to start because the Workstation service did not start.

I can start the Workstation service and all of the other services manually after the computer boots and everything works fine.  Also, I changed the name of the computer and it booted without any errors.

As a test, I shut down the NT machine and changed the name of a Win98 machine to be the same name as the NT server machine name that reported a duplicate name on the network.  The Win98 computer booted without any errors and worked fine.  I then shut the Win98 machine down and renamed the NT machine back to the problem name and I got a duplicate name error.

I reinstalled service pack 5 but this didn't help.

Any ideas as to why I would get a duplicate name error on the NT machine and not on the Windows 98 machine?  I really don't want to change the name of the NT machine.

I removed the remote access service and the computer booted up without any errors.  When I re-installed remote access with only TCP/IP checked, I got the same error.

Is it possible to run RAS on an NT server maching that is not a PDC or BDC?
I am running an NT server which is used for validating users dialing into our system, and it is running RAS - but it isn't a domain controller. So, if I understand the scenario correctly, my answer is that it's possible.

I had a spare com port on my BDC so I moved the modem to that machine.  I'll try again later, maybe with Windows 2000.


Thanks for the help.
