I had the flopping between 100mbps and 1gbps problem with some Intel cards once - some of the machines in the lab were fine, others kept switching back and forth. We eventually narrowed it down to the cables we had hand-made; some of them just weren't up to snuff, and the NIC apparently decided that it had to go back down to 100. I think you should switch your gigabit switch out for a 100mbps switch and see if the network becomes more reliable. -Mike
