Hi All,

Speaking of the Task Scheduler, I just fixed an
issue for a customer that is interesting.

He had me change when his backup was scheduled
so as not to interfere with a synchronizing program
with his web site.

Problem, his backup stop triggering.ÿ It worked fine
when run manually.ÿ After considerable hair pulling,
I decided to examine the XML code directly.ÿ Found
the problem right away.ÿ Somehow, the XML had been
changed from:

ÿÿÿ <CalendarTrigger>
ÿÿÿÿÿ <StartBoundary>2025-05-28T06:10:00</StartBoundary>
ÿÿÿÿÿ <ExecutionTimeLimit>P1D</ExecutionTimeLimit>
ÿÿÿÿÿ <Enabled>true</Enabled>ÿÿÿÿÿÿÿÿÿÿÿÿ <----- the correct value
ÿÿÿÿÿ <ScheduleByDay>
ÿÿÿÿÿÿÿ <DaysInterval>1</DaysInterval>
ÿÿÿÿÿ </ScheduleByDay>
ÿÿÿ </CalendarTrigger>

to

ÿÿÿ <CalendarTrigger>
ÿÿÿÿÿ <StartBoundary>2025-05-28T06:10:00</StartBoundary>
ÿÿÿÿÿ <ExecutionTimeLimit>P1D</ExecutionTimeLimit>
ÿÿÿÿÿ <Enabled>false</Enabled>ÿÿÿÿÿÿÿÿÿÿÿÿ <----- the changed bad value
ÿÿÿÿÿ <ScheduleByDay>
ÿÿÿÿÿÿÿ <DaysInterval>1</DaysInterval>
ÿÿÿÿÿ </ScheduleByDay>
ÿÿÿ </CalendarTrigger>

Changed it back to "true" and now they are backing up again.
I could never find the problem in the Task Scheduler's edit,
but I could have just missed it.

So the tip is if you want to look at the XML code, right click
on the task and export it.ÿ Then open the saved XML into
notepad and make your changes.ÿÿ Of coarse save them.

To import them, you have to right click on the task again
and delete it.ÿ Then on the Scheduler's right pane, import
theÿ XML you just altered.

Just not be on the safe side, make a backup copy of the
original XML you saved before altering things.

My hair should grow back soon.

HTH someone else,

According to the discussion here, AVG was doing this.

Apparently it is an overzealous interpretation of "Do not disturb" in AVG :-/

Is there nothing that antivirus programs cannot do ?
