keyboard not working server 2003

[ozzy]

Help please, came in this morning and the only keystrokes working on one of our servers (server 2003) are back space and enter, can remote in to it not problem, can't see anything wrong in the event veiwer and all seems right in device manager, I'm sure I've seen this before but can't for the life of me remember what caused it, it's prob just me being thick and a hot key or somthing I've tried a another keyboard and a restart with no joy and there has been no updates or anynew hardware added please help
