I am Using NT4 server and having around 100 PCs on LAN.
Suddenly the server stopped its workstation service and the event viewer shows the error message "Duplicate name exists on the network".
I have checked all the node but there is no duplicate name on the network.

Please help....
What is the problem? How can be rectify?.

Thankx

Hmmm, we used to get the same problem on our PDC when the Administrator was logged into more than one workstation. The "Duplicate Name" referred to the username rather than the machine name.

Try using NBTSTAT -c to get a list of the netbios cache. It should list the machine/username that's causing the conflict.

To be honest, I've never seen a duplicate name error stop the workstation service before. It would usually only affect network services.

I'd say rule out the duplicate name first, then see if the workstation service stops again.

Hope this helps,
Gary

YOu just isolate that machine from the Network.Login using cached profile.Then You may identify the real problem.

Or Just the Rename the machine,reboot and check.

You will get this error if your server has two NIC cards, and NetBEUI is installed on each adapter. NetBEUI is associating the different MAC address of each card with the same NetBIOS host name. You need to disable NetBEUI on one of the NICs.

Try this

Reboot the server, and while it is down, pause the WINS service on any servers in the same segment that run WINS service. You will then find that the server will startup perfect, restart the WINS when your happy. To resolve this take out any references to that server in WINS. Use lmhosts to enable name resolution if you really need to.

Duplicate name error points on duplicate computer name on the network.

Even on different workgroup (if you combine P2P and domain-oriented network), computer name is still need to be unique.

Duplicate name requires you to go to the computer one-by-one to find it, since it would not be displayed in the browsing window.

Sorry, incomplete answer.

In case of WINS, then you should check whether there is a static mapping for certain computer.

Static-mapped computer should be removed as WINS would register the computer automatically.

So you would need to checkthe WINS setting in server and also the WINS setting in client Network TCP/IP settting.
