gMSA for scheduled task.

_{Wednesday, May 8, 2019 4:05 PM}

I'm down to the 4th and 5th pages of google and cannot get this to work. I have the GMSA setup correctly and can apply it to services no problem. I want to apply it to scheduled tasks and I've seen where this is supported but you cannot do through GUI. Via powershell I should be able to run "schtasks /Change /RU "domain\gmsa" /TN "task name"

Leave password blank.

thing is this worked once, then I reversed the change to test again and now I get.

ERROR: no mapping between account names and security ID's was done.    I cannot find anything as it relates to scheduled tasks and this error.   any idea's?  I really want gmsa's to work in scheduled tasks I feel it'll be better than standard service accounts.

EDIT:  I have read the blogs on creating the task via powershell.  I want to change existing after I've created.

EDIT AGAIN:   The devil is in the details and I dug so much I missed the obvious, hope this helps someone else.  the command missed the $ after account name.

"schtasks /Change /RU "domain\gmsa$" /TN "task name"

Please refer to this link below:
