Hello! I use Virtual PC to install Win 2000 Pro and Win XP. These has a same problem. After I install these 2 OS, they shows that network card(Intel 81140)is not install correctly. And I re-install it, the problem is occurs. But I can use that LAN card at host computer to internet through PPPOE. How to solve it? I use Asus P4P800-X and on-board Lan card Realtek 8139. I try to do that in other PC with same class LAN Card. That is OK.
