This is too often related to virus, worm or trojan infections.
It is also possible for a POLICY to be in place to disable the task manager, but people tend to ask their IT staff about that. In all other cases, its meant a virus/worm/trojan or other bad news.
You have a backup of what you can't lose before it explodes?
