Duplicate name exists on the network.

By gdatir ·
I've a NT 4.0 PDC & BDCs. I've mixed win95,98, winnt4.0 & win2k clients. I've DHCP & WINS server configured for name resolution.
Till now all the win2k clients configured with wins to connect to the winnt 4.0 domain. Now since last few days the win2k when they start display an error message "A duplicate name exists on the network" & they cannot Authenticate with the PDC. Due to which they cannot access any network drives. Still internet works properly & outlook email works fine. I've checked for any duplicate names in the network. Can anyone help in this regard ??? Pls. help !!!

your computer's netbios' name already exists on the network. to resolve this, right click on My Computer, go to Properties, go to Network Identification Tab, go to Properties, and rename your computer. Make sure that the computer name is unique in the network since netbios has a flat namespace.

I've changed the computer name several times & there is no duplication on the network. Thanks for your help buddy.

The name specified may be the Username. If you have created a user account on the Win2k machines locally as well as on the Server this message will appear. This will also cause the typical profile problem of profilename.domain or profilename.000 also caused by recreating the profile without deleting the original.

Have you tried removing the PC from the domain, deleting the computer account from server manager then readding the PC to the domain?

I've only ever seen that message when trying to add a PC to a domain using a name I had before but didn't removefrom server manager.

I couldn't explain why it would happen suddenly though.

Try deleting these entries (duplicate names) in your WINS server. Then reregister your W2K workstations with WINS.

I'd definitely go with a WINS problem. Read
MS article Q242053 on Duplicate Names on the Network. It will help you to clean up your WINS.
Good Luck
