XP Workstations hang when non-DC Win2K3 server is down

I support 50 Windows XP Pro SP-3 workstation PCs that are all Active
Directory members. My users log into AD accounts, and all their data is on
Server1, also an AD member. It’s not a domain controller, but it runs WSUS
and is the Windows Update server location for just these 50 workstations.
The
workstations are set (via group policy) to check for updates every 22 hours
and install daily at 8:00 AM. The following took place between 2:00 PM and
3:00 PM:

Server1 has several shares. Due to problems with an external RAID array, the
server was still running, but some of those shares were unavailable for a
while, including the share where the VB Script login script is located. In
fact the only shares that were still available were relatively unimportant.
This caused no problem other than missing drive mappings that were done in
the login script. The server was restarted several times during the period
when the shares were unavailable, and the workstations performed normally
when it was up and running.

When Server1 was shut down, all the workstations started to hang for long
periods, even after a restarts. E.g., a 30-60 second delay from clicking on
the start menu till the menu was displayed. The same to open IE. They would
periodically “break free” and would run at normal speed for a few seconds,
then would hang again. During these times, Task Manager showed 99% idle and
almost no network activity. Technet’s Procmon.exe also showed very little
activity of any sort. There were no unusual entries in event logs.

As soon as Server1 was started, the workstations started performing normally
again.

It seems that the workstations want something from Server1, but I can’t
imagine what it is. Only a small portion of the event logs I examined had
any Windows Update activity, probably because the “check for update” time is
randomized.

Can anyone shed any light on this?

Thanks.

Hey Mike,
We're having the same problem when our main file server went down. XP
workstations appear to continue to try to connect to the shares causing them
to hang. We are looking for a solution where people can continue to work
locally without being logged in to the domain OR we can set the workstations
where they don't continually look for shares if they aren't available. Your
problem sounds a little different in that maybe your workstations didn't have
a mapping to Server1 at all. Did you ever find an answer to your question?

No answer yet. That server's name appears dozens of times in the registry of
one of the standard image XP workstations, and I've installed a lot of
software in that image from a server share. I guess I need to get out a
network analyzer and see exactly what they're trying to talk to.
