The problem is thet you have a machine name which is the
same as the domain's NetBIOS name.

This is a mis-configuration.

Any client machine trying to register its workgroup name ( the domain's
netbios name, 'COMPANY' ) is being rejected by the wins server as being
taken by the server whose machine name is 'COMPANY'.

The correct fix is to re-name the server to something other than 'COMPANY'.
There is nothing to fix on the clients.

Shutting down the WINS server has only stopped the error messages, not fixed
the problem.

After you fix it, on the clients, you will then see all the names are
correctly registered.
Here's the sample output of 'nbtstat -n' on a client:

C:\Documents and Settings\Ron.HOMENET>nbtstat -n

Local Area Connection:
Node IpAddress: [81.187.191.70] Scope Id: []
