Duplicate Name Exists on The Network

Hi,

Using a Windows 2003 server called LondonServer, i'm trying to access a share on an SBS 2003 server on the same network called ManchesterServe.

However, when I try, I get the following error:-

\\manchesterserve\

You were not connected because a duplicate name exists on the network. Go to System in Control Panel to change the computer name and try again.

I've checked in WINS on both servers and no duplicates are listed. Also, I'm the administrator and I'm almost positive that no duplicates exist. Especially with the names Londonserver and Manchesterserve.

Any ideas?

Thanks
Dan

Did you also check DNS (are you using aliases)?

There is also a VPN from another office which is the PPP/SLIP connection.

I checked DNS and couldn't see anything obvious.
A bit of background information.....

Londonserver was their old server which they still use as it runs some software that was too complex to transfer. It has active directory installed but it isn't used and i'm worried that if I remove AD from this server, it will cause problems with the software installed.

Manchesterserve is a server that they brought down to London when the Manchester office was closed. It is the DNS server and an SBS server. It has the Active Directory and Exchange used by all computers on the network.

That works. And due to your suggestion, I found an incorrect entry for Manchesterserve in LondonServer's HOSTS file. I've removed it but its not working using \\manchesterserve\ yet. Might need a reboot.

You had a NetBIOS name alias "Server" on one of your servers?
