Not sure about W2K...
Just tried what you suggested on my W2K box (only it’s called Utility Manager instead of Narrator) and my blasted computer started talking to me. Didn't even know what Narrator was until just now. From the Utility Manager you can select Narrator and there is a check box (Start automatically when Windows starts) that might be checked and causing his problem.
In XP, a small dialogue box comes up that presents you with options for Narrator, including exiting the program. Of course, one can always kill the process in Task Manager, too. That checkbox you mentioned should help.
