Hi Jim, I havent used 2K but I think it may have the SFC.exe like XP has.
I think you may have a damaged or corrupted file in the registry.
If you go to Start and Run and type sfc /scannow and click ok it should check and hopefully repair it if I am right.
You will need have to have your 2K cd handy as it will ask for that to replace any dodgy files from
