I've got a scheduled task that needs to run for a user at a specific time. However, the user sometimes logs onto one machine, the next day onto another, then next week onto yet another. At some pint during the day, the user might have to log onto another machine.

How do I get the scheduled task to run regardless of which computer the user is using?

I could of course create the task on all computers, but that seems a bit overkill. Running a script on log on (or a group policy) to create the task doesn't seem a good method either. Any ideas? Basically I want the scheduled task to be defined on the user instead of on the computer. If in the end I need to choose between the two options above, which is best?
