This alert indicates that it is not possible to tell which current Group Policy objects (GPO) are applied. The system will assume that all GPOs have to be applied. This will consume more CPU time.
Userenv experienced an error applying Group Policy to the domain controller. Group Policy must be applied successfully for domain controllers to function properly because domain controllers get several critical permissions, such as Access this computer from network, through policy.
Because of the architecture of userenv, Microsoft Operations Manager (MOM) is unable to directly report the specific problem.
Windows cannot read the history of GPOs from the registry. Continuing Group Policy Processing.
