I have a Dell 2950 with dual Broadcom BCM5708C NetXtreme II GigE (NDISVBD Client).
I have an issue with my Windows Server 2003 Std R2 dropping its network connection intermittantly.
The drops are random with no rhyme or reason.
I have eliminated IP conflicts, power save options, etc..
Could it be the NIC's themselves? Possible a driver or firmware issues.
Dell's answer was to send somebody out to replace the motherboard. That didn't work either.
