I am getting this event in event viewer whenever I restart my win2k server.

"A Duplicate name has been detected on the TCP network. The IP address of the machine that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state."

When I use nbtstat -n command it gives the following :

Node IPaddress:[202.71.140.97] Scope ID:[]
NetBios Local Name Table
Name type Status
--------------------------------------------------
INet~Services <1C> GROUP Registered

As well I have checked all the machine for the same IP address as well the netbios name.
Still I am getting this error.

How can I resolve this problem???

Thanks
Deven

aparantly you are on a domain controller. I have run into this several times as a customer likes to rebuild computers. You will need to remove the computer from the domain controller computers list under domain users and computers.

Try deleting the computer name in the WINS if you are using any. The client that is connecting to the domain have different IP but the same computer name in the WINS database. It is much better if you could search the WINS database both for the IP and Computer Name. This is the same with DNS records as well.

Basically what is conflicting is a name, not an IP address. This happens when you log on to more than one machine concurrently. The username of the logged-on user gets registered as a NetBIOS name, then if the same user logs on to another machine the conflict occurs. 99.9% of the time it is non-critical - I've never come across a situation where a name conflict of this type has caused disruption...
