Windows – Scheduled tasks in Windows Server 2016 don’t run after being disabled then enabled

windows task schedulerwindows-server-2016

I am having a problem with the Task Scheduler on Windows Server 2016 not running repetitive tasks after they are disabled and re-enabled.

I create a task with a “Triggers->Start” of five minutes in the future and set the task to run every five minutes. The “Settings->Run task as soon as possible after scheduled start is missed” option is checked.

Everything works fine – task runs at the scheduled Start time and then runs every five minutes.

Disable the task and wait more than five minutes.

Enable the task, it does not run again.

The Next Run time continues to update every five minutes but the task does not run and the Last Run Time is never updated.

There are no entries in the Task History once the task is re-enabled and no events in the Windows event logs.

When the start time is hit on the next day the task starts running again but this is not desirable as there can be a long delay between when the task is re-enabled and the start time comes again.

Best Answer

The task was set to run every day and repeat either indefinitely or daily. I changed it to Run Once and repeat indefinitely and it resumes execution when the task is enabled after having been disabled.

I think this works because When set up this way the scheduler displays "After triggered, repeat every 5 minutes indefinitely." So once the task is triggered it remains in the "triggered" state even when disabled so once enabled again it resumes running on the schedule.

NOTE: when first setting up the task the start time needs to be set in the future so that the task is triggered for the first time.

No, it won't execute. The Task Scheduler in Vista and 7 can be configured to run missed instances, but XP's cannot. See the checkbox below called Run task as soon as possible after a scheduled start is missed.

However, all three can be set to wake the computer if it's asleep or hibernating.

Windows Task Scheduler – Run Task After Windows Service Starts

You can do this using Task Scheduler with a Trigger set up as follows:

Begin the task: On an event

Settings: Custom

Click the New Event Filter... button

Select the XML tab

Check the Edit query manually checkbox

Click the Yes button

Enter the following in the text box, replacing your service name:

<QueryList> 
   <Query Id="0"> 
      <Select Path="System"> 
         *[EventData[Data[@Name='param1'] and (Data='YOUR SERVICE NAME')]] 
         and
         *[EventData[Data[@Name='param2'] and (Data='running')]] 
       </Select> 
   </Query> 
</QueryList>

More information on XML Event filtering here: Advanced XML filtering in the Windows Event Viewer.

Note: When using a non English Windows 'Data' for 'param2' depends on the system's language. E.g. for a German version of Windows it is 'Ausgeführt' instead of 'running'.
