Currently have a network with 10 Windows 7 pro pcs and each has an expmode. If I set the Windows 7 card to 1 gbps, not auto negotiate, xpmode works great. If I assign the xpmode pc it's own network card (the pc now has two) performance is better but takes a chunk of out of my bandwidth. Each Windows 7 pc and xpmmode pc has it's own IP address and is part of the domain. What if I do NAT? or SHARED NAT? What happens to my xpmode?
