Did you say 512mb ram running SBS 2003 server? That's barely enough.

The speed from server to workstation at 4X less than the reverse is very

suspicious. I would question your network/cards/wiring which you really

didn't give details of.

As far as gig goes, ethernet is a collision scheme. You can expect about

35% of rated performance assuming collisions are kept to a minimum by using

switches. Gig is 10 times faster than Fast Ethernet, 100X faster than

regular ethernet.

If the network is not concentrated in a switch, change it out immediately.

In ethernet, one bad NIC on a hub can cause all the symptoms you're

describing.

Best practice: This is way too many workstations for such an old server.

They should have at least 2 gigs memory in the server of a newer machine.

Upgrade the networking if it's not gig and get a switch which is all gig

(autoswitching for the legacy machines). Make sure you put at least one gig

NIC in the server no matter what you do after upgrading the hub/switch.

BTW, find out if the wiring was field installed by somebody who had a

scanner to certify it or if it was done ad hoc by a shlep. If the wiring

isn't factory terminated or certified in place you could have a problem

there.

What OS are the workstations running?
