Terminal Server

Hi all,
I just rebooted my NT TS,SP6, and all I can see is a black screen with the Windows TS logo at the bottom of the screen, and the cursor. It does not load the GUI and when I tried ctr-alt-del it does not bring the task manager. I cannot turn it off unles I press the power button, but obviously that’s not my concern. I just want to be able to get in. Thanks for your help!.
