access to your logon server has been denied

Hello,

I am setting up a new Windows Server 2003 System for the
company. There is only one server in this network. DNS
and WINS are enabled and appear to be functioning
properly. We have several Win95 and Win98Se workstations
that have DSCLIENT installed on them.

The problem that I am running into is at the workstation
level. Users are able to logon to the server but, after a
period of inactivity, they:

1. are unable to access their mapped shares. The message
received at the wkstn is "G: \\server\sharename is not
accessible",

2. are unable to browse the NT server via Network
Neighborhood. The message received is "The Network is
Busy",

3. are unable to log out and log back in (without
rebooting). The message received is "The domain password
you supplied is not correct, or access to your logon
server has been denied".

So far, rebooting the wkstn has allowed them to logon to
the server again, but then the above scenario repeats with
regularity.

Several reviews of the Event Viewer logs have revealed no
significant warnings or errors with respect to this
problem.

Any assistance with this problem would be greatly
appreciated. Thank you in advance.

Have a Great Day!!

Regards,

Frank
