Supportability and Vista UAC

Supportability is a topic near and dear to my heart.  Vista has made great leaps and bounds in this area  with more logging than any prior OS, as well as a great help file and improved errors.

 However, the other day I was playing with Vista's UAC features and manifests and noticed an error which doesnt really give an indication as to what the real issue is so I thought I would note it here.

When I launched an application with a valid manifest I would get this error:

The error really didnt tell me much but I did recall that I had set some UAC policies earlier  in this domain.

 Under Security Options---  User Account Control: Only elevate executables that are signed and validated

Ahhh this was the culprit. Sho' nuff , I reverted this and it all worked out.  However, had someone asked me why they got an error "A referral was returned from the server" in relation to a UAC issue - I never would have guessed this was the cause...

 Maybe it'll help someone someday..
