We have a Dell Poweredge 2900 server running SBS Server 2003.
Randomly client computers will freeze for a few seconds (3-10) when
doing anything from opening a program, to trying to open a file in
Excel. Anything that requires the network.

Dell has replaced the motherboard twice and all the ram with no
solution.

What would you suggest to look at next?

There are no errors in the event log.

Have you ruled out anything to do with your antivirus program? I've had very
slow network performance, although not what I'd call freezing, if my
antivirus program was set to scan network drives.

I'd swap out the NIC as a test - also the switch & patch cables to try &
isolate the problem.

As SBS does many things its own way I also suggest you post in
microsoft.public.windows.server.sbs - I'll set up this reply to x-post
there.
