I repaired IE 5.5.

I reinstalled IE 5.5.

I reinstalled SP6.

Nothing worked.

Finally I tried the link you posted, messed around in the registry, and tried it again. Finally! The computer can start the scheduler service on its own lol. Obviously there was a problem with the Task Scheduler installed by IE, but - since there really is no way to completely uninstall IE and do a clean re-install, this will have to do. It'll probably work better this way anyway
