Keyboard Shenanigans

This is a wierd one.
I have a Windows 2008 Server that i use as a web server.
It has been in place a while, when i have come to it today the V and T keys are not working. If i open the on screen keyboard the same keys fail to work.
I read something about a registry problem that may have caused this.
Please can anyone help, as i cannot log my server on.

cheers
