I hesitate to give advice on an IIS install, but corrupted files happen more often than you might think since MODx uses literally thousands of files.
I really think you should ask in the MODx IIS forum first, though (if you haven’t already), and see what people there have to say. For all I know, this might be a common problem there.
Bob, I appreciate your help. I will continue this over there.
