We are on Vista, and we have problems with D3D. Another problem, even without RDC is the security that IT put to log off the machine if it's not used for 15 minutes. That's okay, but certain D3D applications would lose the device, and would not restore it correctly. (That to be said, it's just way easier to write the said applications without thinking of recovering from D3D LOST DEVICE. It's real pain in the ass to get this working, especially if you have to put 1GB of vertex buffer/images data in memory, and expect to be there).
