Did you reinstall your OS after the SP2 update failed? If not, then you are most likely running on a busted OS to begin with. It's =possible= that the update bombed out and at just the exact point where nothing was damaged, but this is Windows we are talking about. The odds are extremely in favor of the busted update having done things that only an ubergeek, or a reformat and reinstall can cure.
