estradac, I don't have a solution yet but am close....will post when done.

1.check registry for kb824146 on xp and 2k PC's
2.if exist do nothing
3.if does not exist use tcqrunas to install the patches using the Domain Admin account

hopefully this will allow me to leave the critical updates in place one after another with the checks being quick....until the next SP.

I have exactly 20mins experience with tcqruns, but i'll have a script to post in a day or so. If anyone has any ideas till then i'll keep my eyes open.
