I have an Asus Extreme II motherboard with onboard chipset for ethernet. Running Ubuntu 11.04 Server with VirtualBox. The Windows 2003 Server guest, doesn't recognize the network adapter. Installed the proper driver but getting error 1722, same machine runs xp in another VM fine. Network adapter is set to NAT, installed a newer version of the driver than what Windows was using, but it still doesn't recognize the network adapter. Any help would be appreciated.
