Error message when starting Task Scheduler

Sorry for the multi-post (previously posted to the vista general group with no
answer and I forgot to also cross-post to these maintenance and security
groups).

Suddenly when I open Task Scheduler I get the following error message:

"An error has occurred for task Reminders - XXXXXXXX. Error message: The
specified account name is not valid."

(XXXXXXX represents my account name and it IS my VALID account name.)

Can someone guide me in the steps necessary to get rid of this error?

Sounds like one of your scheduled tasks is trying to use a username that
doesn't exist or doesn't have sufficient rights.

What is in the event logs?

I am the only user on this computer. The only other account is Guest (which has
been disabled).

I can find nothing (nothing that seems pertinent, to me anyway) in the Event
Logs.

This just started suddenly. Up until yesterday, I could access the Task
Scheduler with no problem at all.

I'm having a similar problem. I can create a new Task Scheduler task
without any problems using a local account, but when I configure it to
run under a domain account, I get the error message about "The
specified account name is not valid." This account is valid, is in
the local administrators group, and isn't disabled or locked out. I
don't get it.

If I create a new task and have it run under the domain account, I get
the same problem.

%@$^ Vista piece of junk. I can't believe Microsoft spent 5 years on
this OS.

I came across this error after syspreping a Windows 2008 server (basically changing the computer name), Fix will also apply to Vista
