I agree with this. Run spybot and adaware on the server and all the client pc's.

I would also delete the Normal.dot template from the Word directory. I forget what problem this actually fixes, but it's worth a shot as well.

I would also make sure that every computer is completely up to date with their windows versions AND their office versions. Other than that I can't think of any other suggestions, but get the actual error message along with the error code next time you go back.
