A duplicate name on network....

I am always getting the "A Duplicate name has been found on your network......" error on one of my servers that is also a DC.  If I run an nbtstat -n on it to find out what's going on, I get (3) listings for the server name (1F, 00, 20), and (3) listings for the domain name (00, 1C, 1E).  Isn't that the correct listing?  How can I *really* find out who is causing the duplicate name error?  Thanks.

Ok, I have some more time for a response now. THis can also occur with printers in a XP/2000 environment. I have seen an issue similiar. Here are the details.

Problem:
A printer was set up on a computer and shared.
The printer had a name (Admin).
A network was set up with AD and a computer was added later named (Admin).
Computer Admin started to randomly generate Duplicate Name popups.
Printer began having intermittent printing failures.

Resolution:
All print drivers were removed from all machines.
Printer was reinstalled and shared with a different name.
Machines reconnected.

All worked.

I'm not doing anything, it's usually in the wee hours of the morning.  Those articles didn;t really pertain to me, so I'm still looking for help.  Thanks.

I have had an issue in the past in which a server would get the same message and there was not another server, workstation or device on the network with the same name. The issue had to do with a process which was actually pointing to itself. In my case the server had the name "Exchange", and that was an issue in the enviroment. But, it did not cause any problems. So, it could be quite a few things...

In your case it could be a computer or workstation that is set to workgroup with the same name as the domain, it could be that you are using split-dns and the name is used externally, etc.. Let me know if this server has a really generic name, how many dcs, are you running WINS, DHCP? and anything else you can think of.
