Issue with Task Scheduler launching a task

Question

I have a task scheduled in my Windows 2008 R2 machine but it failed to trigger with the following error in the log (Event logs).

Error:

Task Scheduler failed to start "\Hyatt_International_Distribution" task for user "SAFFRON3\cb_admin". Additional Data: Error Value: 2147943645.

Task Scheduler failed to start Task Engine "" process due to an error occurring in "LUAIsElevatedToken" . Command="taskeng.exe" . Additional Data: Error Value: 2147943645.

The complete error is as below:

The task is set as: Run s if user is logged in or not, With Highest privileges, Power: Start when on AC power, Allow task run on demand.

The task runs almost everyday, correctly, but failed yesterday. Any particular reason?

Answer 1

On properties,

Check whether radio button is selected for

Run only when user is logged on  

If you selected for the above option then that is the reason why it is failed.

so change the option to

Run whether user is logged on or not 

OR

In other case, user might have changed his/her login credentials
