Hello create_share,
Thank you for posting in Microsoft Community forum.
Did you run Update-LapsADSchema first?
If so, is the Test (Set-LapsADComputerSelfPermission -Identity Test) an Organizational Unit (OU) name with Computer devices?
*Secondly, how to enable permissions for an OU having a space in it? For Example "Desktops HO"?*A: You can try to use as below
Set-LapsADComputerSelfPermission -Identity "Desktops HO" Or Set-LapsADComputerSelfPermission -Identity "OU=Desktops HO,DC=domain,DC=com"Get started with Windows LAPS and Windows Server Active Directory | Microsoft Learn ****
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
