Issue with Task Scheduler launching a task
scheduled-tasks
Solution
My task was set to `Run only when user is logged on` and it was failing for me even while I was logged in and starting it manually. The user was set to me already. No password changes, etc.
I solved it by clicking "Change user" and selecting myself again.
I suspect it may have been caused by AD changing the user SID or something to that extent. Perhaps IT was doing some user management in AD, who knows.
Problem
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: Log Name: Microsoft-Windows-TaskScheduler/Operational Source: Microsoft-Windows-TaskScheduler Date: 4/16/2012 9:59:59 AM Event ID: 101 Task Category: Task Start Failed Level: Error Keywords: User: SYSTEM Computer: xyz Description: Task Scheduler failed to start "\Distribution" task for user "SAFFRON3\cb_admin".
