Scheduled task gets deleted/missing

[compsosinc]

Using XP Pro SP2. I setup a scheduled task to run a batch file (*.bat)
daily at 7am. The task runs fine but eventually it gets deleted from
the Scheduled Tasks. The first time it was deleted/missing, it had ran
for 2 weeks, and I thought someone else had accidently deleted it. Now
it is deleted/missing again, and it ran for over 3 weeks.

Any ideas?

Thanks

Task are stored in c:\windows\tasks. They get deleted by
human intervention or by malicious code, not by Windows.
You could home in on the culprit by creating another task
that runs the batch file below once every five minutes. It
would tell when your task gets deleted.
@echo off
if exist c:\Windows\tasks\MyTask.job (set deleted=No) else (set deleted=Yes)
echo %date% %time:~0,5% Job deleted? %deleted% >> c:\test.log

Replace "MyTask" with the name of your disappearing job.
Examine c:\test.log every day until the problem occurs again.
