Note: This applies to pre Vista operating systems.
If you are running on Windows 8 or Server 2012 then see the kb After Upgrade to Version 5 all scheduled Tasks became Unsheduled. Attempts to set a time doesn't schedule them.
Possible causes and resolution:-
- Check that the Windows Task Scheduler Service is running.
If it is not the restart the service.
- Check if it possible for the user to create a Windows Scheduled Task. If the following error is displayed:-
"The new task could not be created."
"0x80070005: Access is denied. Try using the Task page Browse button to locate the application."
The the cause will be a permissions issue with the c:\Windows\Tasks Folder.
- Open a Command Prompt
- Move to c:\windows
- Run the command below
CACLS Tasks /E /G builtin\administrators :F
This should reset the Access Control Lists and give full permission to the Administrators Group to the folder.
