Scheduled tasks copied between servers often do not run

After copying tasks between servers and applying passwords, the copied task
often does not run on the target machine.
It seems the scheduler simply does not see the task until it has been
manually run once.
There is no status message and no entry in the log to indicate any cause,
and the last run/next run times never change.

We are migrating nearly 200 tasks from old servers to new servers, and
cannot just run these tasks at anytime to force them to run automatically
thereafter. The scheduled tasks run-times are distributed over 24 hours

The method used to copy the tasks is:
1. RDP to the old server and copy the tasks to a network folder using drag
and drop in Windows Explorer
2. RDP to the new server, drag and drop tasks into C:\Windows\Tasks.
(Occassionally Windows Explorer crashes when pasting, but tasks still
arrive
3. Apply passwords.
4. Wait and hope!

Can anyone propose a solution or point to a problem ticket somewhere?

*** How can you tell?

*** This is incorrect.

*** You can do much better - see below.

So far you claim that some tasks do not run appears to be
largely based on guesswork. To be sure you MUST inspect
the Task Scheduler's log file. You should also embed your
scheduled task into the batch file below, then examine its
log file. I suspect that it will reveal a lot!

@echo off
echo %date% %time% Start of task > c:\test.log
echo User=%UserName%, Path=%path% >> c:\test.log
c:\Tools\YourTask.exe 1>>c:\test.log 2>>&1
echo ErrorLevel of c:\Tools\YourTask.exe=%ErrorLevel% >> c:\test.log
echo %date% %time% End of task >> c:\test.log

When I said there was no log entry, I mean that literally, nothing appears
in the log for the task until it is run manually.
It is not a claim, and it is not guesswork.
The tasks just do not run and there is no record.
We take a daily copy of the scheduler's task log to avoid the 32k
wrap-around.
Each of the tasks records its own log if started. They were never started.

Once they have been run manually the first time, they schedule normally
thereafter.
Approximately 70% of the tasks so far copied in the manner described do not
start on the first day,
on the next day etc until run once. Detailed inspection of the task
properties using the little
Microsoft Tasks utility (cannot remember its name) shows nothing out of the
ordinary.
The properties on the target machine replicate those on the source machine.

This problem has applied to tasks copied from 4 different servers with
different images, to 4 different servers
two of them with different images, so it is not an isolated problem but
generic in our installations.

Thank you for your reply.

In such cases it's a good idea to go back to basics. Schedule
the batch file below, check its output and the Task Scheduler's
log file, then modify it to run the tasks that YOU want to run.
This will soon tell you why it fails. If you still have problems
then you should post the contents of the Task Scheduler's log
file. You should also examine the Event Viewer for relevant
entries.

@echo off
echo %date% %time% Start of task > c:\test.log
echo User=%UserName%, Path=%path% >> c:\test.log
cacls %systemroot%\system32 1>>c:\test.log 2>>&1
echo ErrorLevel of cacls.exe=%ErrorLevel% >> c:\test.log
echo %date% %time% End of task >> c:\test.log

Thank you.
I will check the Event viewer, it must be worth a visit for sure.
I can try to reproduce the behaviour with just a stub cmd file like you've
enclosed,
going through the copy process I described before to try to reproduce the
behaviour.
The utility I mentioned is JT.EXE
We are implementing dynamic Job monitoring across all the servers using
Rendezvous messaging
and our own utility which will allow remote task management - that may solve
the problem
because it will allow us to copy tasks from one server and create a
duplicate on another
without going throught the RDP,copy,paste,RDP,copy,paste process

I assume the scheduler just scans the Windows\Tasks folder and requires no
registry entries for tasks. Is that so?
And if so it is very hard to see why jobs are getting skipped....

Thanks

Yes, the Task Scheduler relies totally on %SystemRoot%\tasks.
AFAIK no registry entries are involved.

There are several reasons why a task might get missed. An
obvious one is inappropriate NTFS permissions for the
..job file.
