Or not, but do a Google for Scripting Guys. MS Technet used to run a column by a couple of their script geniuses that would answer a lot of common "How do I do this" questions, a lot of esoteric topics like what you have. Again I don't know if they ever tackled anything like this specifically but good chance there is at least something that might help. There is a Windows help file available you can download that has all of them archived.
