OS: Windows Server 2008 R2 Enterprise
I am unable to get the Task Scheduler to run .bat files while I am logged off. I have a a production .bat file I want to use, but for my troubleshooting purposes I am using C:\Users\Administrator\Desktop\test.bat
test.bat is very simple. All it contains is: taskkill /im notepad.exe
It runs successfully on its own. If I have Notepad open and I double-click test.bat then the cmd window flashes and Notepad dies. The .bat file is not the problem.
The task I created in Task Scheduler is "Test taskkill" (without the quotes). I can see its location in Windows Explorer: C:\Windows\System32\Tasks\Test taskkill
If the task is set to run only when the user is logged on then the task works. With this setting, I can right-click on it > run and I get the same behavior as if I double-click the .bat file. That means the task is configured correctly.
If I set it to run whether or not the user is logged on then when I right-click > run nothing obvious happens. The job is reported as having been run successfully in the history, but Notepad survives. I know that I am using the proper credentials for the account that I am configuring to run the task. That account is the local administrator.
This issue appears similar to issues other have had in the past:
Running a .bat file in Scheduled Task
The thread in the second link seemed to resolve an identical issue for many people with the suggestion that the account used to run the task requires explicit permission to the .bat file and all files that the .bat file modifies. This was very promising (if an annoying requirement). However, I have confirmed or assigned explicit permissions for the local administrator to the following areas, and I am still not successful:
Additionally, I have confirmed that the local administrator account is in the local administrators group.
Am I missing some other permissions that needs to be set? Is there something else I should be looking at? Thanks!
I have resolved this problem with help from a contractor who was doing some other work for my institution.
In the properties window for the task, on the Action tab, when creating or editing the action that opens the batch file (in my case test.bat), there is the "Program/script:" field and there is also a "Start in (optional):" field. I previously had the "Program/script:" field containing the full path to the file, ending with the file name, and I had the "Start in (optional):" field null. This configuration appears to work without issue when the task is set to "Run only when user is logged on" in the General tab of the task's properties window. However, this configuration does not work when the task is set to "Run whether user is logged on or not".
In order to resolve the problem, I changed the action so that the "Program/script:" field contained only the file name, not the file path. I put the file path in the "Start in (optional):" field. This configuration works when the task is set to "Run only when user is logged on"! I have tested with the task running on a trigger and also with running it manually.
