DescriptionWindows cannot do loopback processing for downlevel or local users. Loopback processing will be disabled.
Event InformationExplanation :
This is an informational event that indicates that Group Policy loopback processing works only if the computer and user objects are in either a Windows 2000 or Windows Server 2003 domain. The computer and user objects can be in different domains; for example, one can be in a Windows 2000 domain while the other is in a Windows Server 2003 domain.

However, you cannot deploy Group Policy to users in a Windows NT 4.0 domain by applying loopback to a computer in a Windows 2000 or Windows Server 2003 domain.
