All of the machines have this network card? What is the switch?

You have to go into the control panel, system, hardware, device manager. From there look for your network adapter. Right click on it, choose properties, select the advanced tab. Make sure that your cards settings are at
Flow Control: Generate and Respond
Link Speed: 100Mb Full duplex (it should be default set to auto)
QoS Packet: Match your other computers on the network...probably disabled
Wake On: Your choice
The problems result if you leave it on Auto and it detects half duplex when it should be set to full duplex. I've had problems with our dell computers at work doing this when I migrated to 100Mbps as well. A quick change on the NIC itself eliminated my problems.

I have seen this as well with auto-negotiation on Dell machines, as well as some PCMCIA NICs. Definetely hardcode the speeds, both on the switch (if possible) and on the actual computer. If 100mb-full doesn't work, then try 100mb-half, etc.
