MSSvc.EXE problem

Hello:
When I boot up my Dell Dimension 8200 with winXP installed, I get a message that reads "MSSvc.EXE has encountered a problem and needs to close ". Data in the error report lists 2 files that will be included in the report. I can't find either of these files when I do a search for them, nor is "MSSvc.EXE" listed anywhere as a program. I did a search on this board, which came up with 1 post, and no fixes were listed. I have also researched google and found a couple of possible fixes for this, but niether worked. The items I was to change in the registry editor did not exsist on my machine. I also read that this may be related to a program called "stealthdisk ", which I can't find anywhere either.
Any ideas?
Thanks, Tom
