It would have been so much easier sticking with XP PRO 64. So many little annoying issues such as this one with Vista. I was trying to start WCF service running under its own windows service container and it kept stopping as soon as I tried to start it. So I went to the System event log to see what was going on only to be given this error saying Vista couldn’t show the system event log. Simply clearing the event log will get you moving again.
