Introcution

I want to run a scheduler task using an sMSA user. The user can only be used on the destination machine and the password is managed by the domain. Standalone managed service accounts (sMSAs) are managed domain accounts that help secure services running on a server.

This procedur describes how an sMSA user is created and how to assign it to a scheduler task.

Create and install sMSA user (Windows Server 2019 Version 1809)

1. On the domain controller (DC), create the managed service account and assign it to the destination machine.

Import-Module ActiveDirectory

# Note: Since the *-ScheduledTask* cmdlets are implemented as 
#       CDXML-based *script* modules, they only see preference vars.
#       in the *global* scope - see https://github.com/PowerShell/PowerShell/issues/4568
$prevEaPref = $global:ErrorActionPreference
$global:ErrorActionPreference = 'Stop'

# Setup the scheduled task:

Problem description

I was trying to run TrackGpo from the Windows Task Scheduler by executing the following:

Program/Script: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Parameter: -ExecutionPolicy Bypass -Command "Invoke-GpoTracking -GpoRepo C:\GPO_Repo -WorkingDir C:\GPO_WorkingDir"

Running the task resulted in the following error:
Task Scheduler successfully completed task "\Backup GPOs" , instance "{300bfea1-ba81-4a4a-9350-205a9fd27d76}" , action "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" with return code 2147942401.
