We have a Server 2003 R2 Standard Edition server which has an almost completely black login screen (see attachment) for both the "Press CTRL ALT DEL screen, and also the screen that follows where the credentials are entered. Once you work out which part of the credentials box is in use, you can type credentials and login OK, after which everything is fine.
It happens directly with a VGA monitor and also the same via RDP. The server has been rebooted a few times but no change.
Any suggestions to get the screen back to normal?
