Hi folks,
I have a workgroup which includes Windows XP Pro(1), Windows 2000(2),
Windows 98SE(2) and a LINUX client. All playing together fine, with an
ADSL router providing DHCP. Last night we had a hub disconnected, and when
it was plugged back in, we find that every PC restarted with a message that
a duplicate name exists on the network, and we now can't see each other in
the Windows network neighborhood or access shared folders. The DHCP server
list confirms that only the usual PCs exist with no duplicates, and I can
ping every PC from every PC. We think that the Linux PC may be a member of
a different named workgroup, and that its name is the same as the Workgroup
to which the rest belong - maybe this is causing a problem, but it never did
before.

What is likely to be the cause of this problem and how can I fix it? Thanks
so much for your help.

Regards,
DAvW

I have seen this type of problem reported when a workstation
had the same name as the workgroup.

did you try ipconfig /release and then /renew on the clients?
 
Thanks for the excellent responses. I renamed the workgroup and renewed the
ipconfigs on all PCs and the problem disappeared. We have an external
company who access our application server thru a VPN. He had named his
Linux PC the same as our workgroup. I think that was the main problem.
