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.
