You can use the same technique to enable a V4.1 wireless adapter in Windows Server 2008... w2k8 makes a great (and quick) desktop os with a few tweeks... with the help of this thread I was able to get the wireless adapter up and going (Linksys's driver wasn't signed = wk8 won't activate the driver!) but the Ralink drivers are signed... Had to remove the newtwork adapter from the device manager, but once I did the Ralink install worked like a champ!

Thanks!
