Lose access to shared drive

[Ward]

I have a windows domain with SBS2000 as domain controller
and an old NT Server (v4, sp6a) as a member server. WinXP
clients regularly lose access to a shared drive on the NT
Server. Win98 and Win2000-Pro clients do not lose access.

WinXP clients, on access attempt, get popup window asking
for login credentials. When they respond with username
and password they receive message that "Login
Unsuccessful, user name you typed is the same as the name
you logged in with. That user name has already been
tried. A domain controller cannot be found to verify that
user name."

After user logoff and logon on the XP-client, the user
again has access to the shared drive on the NT Server,
but some minutes later, the access is denied again.

Any help appreciated.

Hi Ward. You might try to temporarily disable the four security options for
"digitally sign communications" on the W2K domain controller in security
policy/security options and. I know there is an issue with smb signing
between W2K and XP, but am not sure about the effects with NT4.0. ---
