Just to add to everything else you received:

At the client's site, do they have 10base-t or 100base-t? Are they using a hub or a switch or a router between the workstations and the server? A switch will greatly increase their bandwidth over a hub because a switch isolates each connection to pure 10base or 100base per connection whereas a hub is dumb and uses the ports for virtually all communications because it does not know that ONLY ONE connection and what that connection is resides off of each port. Also, if it is a 10 base-t connection, not all cards run well set on auto. Sometimes setting a 10base-t NIC to half-duplex (forcing it to that speed) actually runs faster than setting it to auto or to full-duplex because it reduces errors and dropped packets.

Also, if they are using Windows XP, check out the MTU setting on each workstation.
