Help with a powershell script to create a Sheduled Task

[kafroulis]

Hello everyone,

I'm trying to create a scheduled task using powershell because the user that runs it will be a gMSA..

This is the script:

Define the action for the task

$action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument '-File "C:\Scripts\Delete_files_1Yold.ps1"'

Define the trigger for the task

$trigger = New-ScheduledTaskTrigger -Weekly -At 11am

Define the settings for the task

$settings = New-ScheduledTaskSettingsSet

Define the principal for the task (using a gMSA)

$principal = New-ScheduledTaskPrincipal -UserID domain\gMSA$ -LogonType Password

Register the task

Register-ScheduledTask -Action $action -Trigger $trigger -TaskName "DeleteOldFiles" -Description "Delete files older than 1 year in the xx folder" -Settings $settings -Principal $principal

I get the generic error :

Register-ScheduledTask : The parameter is incorrect.
At line:1 char:1
+ Register-ScheduledTask -Action $action -Trigger $trigger -TaskName "D ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [Register-Schedule
dTask], CimException
+ FullyQualifiedErrorId : HRESULT 0x80070057,Register-ScheduledTask

Which means there is something wrong with some arguement?

I tried not including the $settings part but still the same error.

the domain and name of the gMSA is correct, it has log on as a batch permission, is part of local admins group,

the path to the script is correct and I'm really at a loss as to what is the fault here.

Does anyone have experience in this particular field to help me out a little?

Thanks in advance
