hi damnmachine

this may sound like a strange fix....but i had a very similar problem to the one your having there ...also started after i had installed microsoft office.

office had been installed on the desktop...but not on the laptop which is which has a wireless conection to a belkin router.... after the office install couldnt browse any sites with the desktop but the laptop was fine....

anyways...noticed on the task manager that nisserv.exe was using a considerably large amount of system resources.... checked on symatec site and apparently this was caused by a corrupt urllist file in the NIS folder.

deleted that particular file....ran live update to get a fresh urllist..went ok

and now the desktop is browsing fine !!!!!!!!!

dont understand why this would happen....but thats what fixed it for me..

hope its of some help to you
