Optiplex GX280 loses network connection

Question

We just cloned a few new Optiplex GX280's with Windows XP and it frequently loses its network connection.  We have loaded the newest drivers for the PCI-e cards from Broadcom and the problems persists.  Has anyone else experienced random network connection losses with these network cards?

My new 280's seem to working just.  You should be using the driver named Broadocm 57xx.

Could it be a problem negotiating with the switch about what speed to run? We have had this problem from the GX150 series. We set the speed down to half dup/10 Mbs on some troublesome connections, by changing the driver settings.

We found viruses on all machines.  When we cleaned up the virus, all problems went away.  Thanks for all your responses.

I have had several of my GX280 machines have network problems. I imaged about 7 machines and they all worked fine. When I went to deliver them I had 3 machines that would not longer connect to the network at all. One of them I cannot even reimage because the NIC does not seem to work at all now.

I have installed Dells lates BC57XX driver as well as version 7.86 of the driver from Broadcom. I have updated the BIOS too. This is crazy because the one machine I have been using at my desk for about 3 weeks and as soon as I moved it to another location it no longer works.

The crazy part is that it happend with 3 machines.

Did you ever come up with a solution?  I'm tempted to throw another nic in the machine that's doing the same thing.

I warrentied the motherboards and have not had a problem with those machines since.  Replacing the hardware was my only fix.
