Restart NIC on schedule?

Hi,

Is it possible to stop and restart a NIC from a scheduled event, like a
Command batch file automatically executed by Windows Scheduler?

We have a standalone W2K SBS SP4 server that is acting very strange. About
every 24 hours, it just magically stops talking to the network. We've tried
replacing the built-in NIC with a new 3Com PCI NIC, and the same problem
happens. Nothing is registered in the event logs. The server does not seem
to notice that it is offline, but it won't communicate in or out unless it
is rebooted or the NIC is restarted. Power management is completely
disabled, Wake on LAN is enabled, and it still fails.

We're going to rebuild it soon, but in the meantime would like to have an
hourly routine to restart the NIC to keep it alive.

Thanks!

You might consider just using a WMI script, since AFAIK it can be called as
a file.

Have you tried changing the switch port and a different patch cable?

Yes, we've changed both the switch and the cables, same problem. Thanks

Forgive me, but I'm not familiar with WMI scripts - I'll look them up on the
MS Knowledge Base. Also, what does AFAIK mean?

If you're willing to give a simple example, I'm all ears! But I'm not too
lazy to do my own homework!

Thanks!

Have you uninstalled the entire stack and reinstalled it? I have found that
this can cure many strange problems.
