Task Scheduler Error: 0x8007007a (data area too small?)

I am trying to set up a scheduled task. When I create a
task and enter user account information, I get the
following error:

0x8007007a: The data area passed to a system call is too
small

Does anyone out there know what this means, and how to
fix it?

Please note that I DO have a login password, so I am
meeting this XP requirement for the Task Scheduler.

Thanks,
