When a GPO is set to Non Compliant, Attempting to Incorporate Live causes the Error
Error Access is Denied n which function is the Access denied - System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Incorrect permissions of the GPOAdmin Service account on the live Object
When Incorporating Live, GPOAdmin Service account takes the setting that have been made to the Live Object and adds them to the latest GPOAdmin Backup.
The reason for the Error is the GPOAdmin Service account doesn't have the correct permissions on the Live GPO. Make sure that the service account has Edit, Delete, and Modify Security on the live GPO as well as being the owner.
