Do you have any names n your DNS or WINS with that name?  Duplicate records will trigger this.

We do not use WINS and I have checked in DNS to find not duplications.

What error message are you getting in the event viewer? It should give a more detailed reason.

I know this sounds bizarre, but do you have a machine name the same as a local or domain user name?  I've seen that happen before.  The other thing is, do you have a machine that is in a workgroup with the same name as your domain?

The other way of looking at this is to step back and see how long you've had this problem, in which case what has been done on the network since that time?  That will go a long way to isolating where the problem might lie.

Here is what I get in the event log:

The name "GLBB           :0" could not be registered on the Interface with IP address 10.0.0.171. The machine with the IP address 10.0.0.150 did not allow the name to be claimed by this machine.

The implication from the error is that 10.0.0.150 has the same name as 10.0.0.171.  You will of course have checked that and found that it doesn't, right?

I would recommend that yu perform a search through the registries of 150 to see if there are any references to that name in it.  Secondly, check the SID of both machines.  Have either if these machines been imaged?
