Network resources

[Amd]

Hi,

My network consists of a Windows 2000 AD Server which was
upgraded from a windows nt server 4.0. This is also a
DHCP server. The clients consist of windows 98 and
windows xp PCs. I am not able to access the shared
resources on the xp machines from the win 98 pcs. I get
the error message stating that the " \\computer_name is
not accessible. Logon server cannot be found." However
I am able to access the resources on the win 98 PCs from
win xp. Please help me in sorting out this issue.

Thanks,
Amd.
