Task scheduler: nothing happens

[Guest]

I'm trying to configure a task in task scheduler
The task starts running at the scheduled time but the actual application I want to execute is not launched. Actually nothing happens, only the status indicatior in the task scheduler window changes to 'running' .
No error message is written to the event log, no error message can be found in the task scheduler's log file.
I log on as domain\administrator (on a windows 2000 server SP4) and use the same credentials for the task itself
The task scheduler service logs on as the local system account and 'allow service to interact with desktop' is checked. Unchecking the checkbox (and stopping/restarting service) doesn't resolve the problem.
For testing purposes I simply scheduled calculator...
When I execute calculator from within the run box, it starts as expected.
What am I doing wrong?

Thanks.

See if it is running in the background. See tip 4579 in the 'Tips & Tricks' at

The calculator is not suitable to test the Task Scheduler, because the Task
Scheduler is designed to run in the background whereas the Calculater
requires keyboard input. Schedule this batch file instead:

@echo off
echo %date% %time% Start of task > c:\test.log
c:\tools\YourApp.exe 1>>c:\test.log 2>c:\test.err
echo %date% %time% End of task >> c:\test.log

Now schedule your task, then examine the two log files, and all will become
clear.

It probably works because a Command Processor (cmd.exe) is automatically
invoked when running the batch file. This may not be the case for your VB
application. You can force it by using a command line similar to

cmd.exe /c YourVB_Script

I scheduled the batch file you proposed and... it works with my VB application.
No errors, normal execution. Problem resolved.
So that's very good news.
Thank you very much for your accurate help.

But: why does the same (VB) application fail to run when it is launched

from within the "run" textbox in task scheduler? It's exactly the same
application, the same user/password. The only difference is that the
application is triggered from within a batch file.

Hi All,
I got a similar problem on some of my servers. The
applications (I did not use Calculator but Notepad and
IExplorer, and my own DOS scripts) that I tried to
schedule, work just fine on the other servers and I did
not have to code any DOS scripts to invoke to the
applications. Please help.

I suggest you use the debugging technique I recommended
in my first reply to the OP.
