I am connecting two machines using Remote Desktop. The server machine is running Vista Business, and the Client machine is running Vista Unlimited. When my Unlimited machine connects to the Business machine, the Aero Glass interface is not present. The Business machine before connecting was definitely showing the Aero Glass interface (e.g. set to 32 bits, w/ transparency enabled). After connecting it seems the Business version intentionally cripples the interface. Connecting Ultimate to Ultimate does preserve the Aero Glass feature, so it's not the underlying RDP causing the problem. Any answers? Thanks, Mark.
