Broadcom NetExtreme 57xx random failures in Optiplex GX280's
We have several GX280's here at lately we have started seeing some failures with the onboard nic's. The nic is the Broadcom NetExtreme 57xx gigabit ethernet adpater. The failure we have seen is that when the pc's is first powered on in the morning the nic will not initialize. Once Windows comes up it does not see that there is a nic in the system. Rebooting does not fix this. Sometimes it gives an error message of PCI express ethernet bridge has failed, sometimes it does not. The fix that i was given by Dell Gold Support was to unplug the nic, disable it in the bios, save & exit, unplug the pc from the power, plug it back in, reenable the nic in the bios, save 7 exit, plug the network cable back in and boot up. Now this has fixed the problem everytime, but I can't help but feel this is just a work around.
Does anyone know what could be causing this, if there is a permanent solution for it, and what that solution is? Any help you could give me would be appreciated.
PS. The bios on all of the pc's that I have seen this failure is out of date. Could upgrading to the latest take care of the problem?

One of the techs mis diagnosed the DHCP server running out of addresses
as bad nics. Put in a new nic with new mac address and viola it works again
until others come in and logon and use up all the addresses.
The real fix was to allocate more addresses.
Sometimes what "fixes" the problem is not really addressing what is going on.
The other bad nic theory shot down was CAT3 vs CAT5.
Cat3 works fine when you force it to run at 10 meg HALF DUPLEX.
And will even be tolerant of not having proper pairs 1234 VS 1236
wires but BREAKS when going to 100 meg full duplex on the same wire.

After upgrading the bios on all of the GX280's on campus to A08 we had another PCIE NIC bridge failure this morning. While reinitialization cleared the issue we have decided to have Dell replace the motherboard. Hopefully we will be getting a newer mobo that this issue will not resurface on.
