I mentioned something not too long ago about WGA... and how much of a headache it can be.

ARTICLE

Not sure if any of you have had a similar experience as mine, (in a nutshell story) I was doing some work on a server, and each time I replaced some hardware on it, WGA kept asking me to reauthenticate my copy of Windows. Even though my copy was legitimate, it locked me out of my production server saying I had reauthenticated too many times. M$ would not assist me in resolving the issue. They wanted me to pay something like $35 a call to their Tech support to resolve a problem I did not create!

Anyway... some google searches led to several other frustrated people.... and I remember reading something about a file called "AntiWGA" *cough cough buuurp*

Sorry... hairball.
