IISADMIN and W3SVC services stop and disable randomly

Did a fresh install of Vista Premium x64. I am doing various
development with Visual 2005 (Vista SP1 installed) and I randomly have
this issue where BOTH the IISADMIN and W3SVC services STOP, and then are
set to DISABLED. Nothing is sent to the log files so I have no idea
where to go with it. I simply set them to automatic and start them back
up and it works like new. But then randomly, usually a few hours later,
it disables and stops them both. I'm doing nothing consistent when the
services fail, so I haven no idea where to start with fixing this one...

Any help out there as to how to debug this better or maybe a solution?

Thanks!
