Duplicate name on network

Hello all,

I am working on a clients machine that just started this morning telling me that a Duplicate named computer is on the network. The client is running SBS2k3 and xp pro on the client machine. I have already check multiple things and tried multiple things to fix the problem. I first verified that there of course no duplicate computers on the network through active directory and with nbstat -n, when I dod the nbstat it shows no connections. They are running a wireless connection and I have disabled the LAN connection and the 1394 connection, so the wireless card is the only connection. I have verified in that there are no duplicate IP addresses through DCHP, the only duplicate entry I can find is in the WINS server. There are two entries one for workstationa and one for file server, but there are 10 other computers that show this so I doubt that is the problem.
 I have also tried using a static IP that is not in the DCHP scope. Finally I deleted the DHCP entry on the server and then rebooted the client computer, and still says there is a duplicate name on the network. Recently there has only been one computer added to the network but it has a very different name, also I verfied that the hostname is correct for the computer and not a old host name. Any one have ideas?

P.S. - It only shows up on the log in screen once and that is it.

Does the computer have two network connections such as one wireless and one wired?  I used to get a message like that if I had plugged into the network and had my wireless on.  The reason was the wireless was on a different subnet but the two subnets could see each other.

No the other networks connections are disabled.

Could it be that another workstation has the same sysid as the user having problems?
Was his machine loaded with an image?
If so, have you tried using SysPrep?

His machine was loaded with just a straight XP Pro disc, no imaging. I know it can't be user related becuase he can log on the other machines just fine. Also when I log in as administrator I still get the error.

We figured out the problem, there was a conflict with a IP address and a old computer in the WINS server. After we tombstoned the old WINS entry and deleted the DHCP entry the error stoped occuring.
