Re: Curious Loss of Network Connectivity

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

Here are a few questions that may help to troubleshoot:

Have you checked the event logs on the clients and the server during this
period? What events occur?
What devices are between the clients and the server?
Do the clients maintain connectivity to these intermediate devices?
Do the clients maintain connectivity to other servers on the same network?

Four workstations (XP Pro) lose network connectivity to the server (Server
2003 R2 SP2) each evening between 6:30 and 8:00.

Other network workstations do not exhibit this problem. There are no
differences in software running between the workstions that lose
connectivity
and the workstations that don't.

The only thing in common among these four workstations is that they were
all
purchased at the same time from the same manufacturer.

This problem only manifested after the server OS was upgraded to SP2.

I have removed and reinstalled AV software, with no effect. The NICs are
not
going to sleep. I have left and rejoined the domain. There are no "timed"
programs running. There are absolutely no software differences between
these
four and the other workstations that function properly.

Thanks in advance.
