I loaded and tried the RX66787 drivers and they did the same (Code 31) Unknown device for Intel Pro 1000 MT. I ran the Dell diagnostic cd, and the adapter passed tests. I also loaded the Intel provided drivers for the NIC, and they had the same effect as the Dell provided drivers.
Anything else to try...still sounds like a driver issue???
