2.3.2.3 Persistent Data Storage Facilities
The Group Policy protocols require a persistent storage facility to maintain Abstract Data Model (ADM) elements. Examples of such a facility include file systems and databases. If this requirement is not satisfied, Group Policy does not function.
The Group Policy ADM is based on the conceptual models specified in [MS-GPOL] sections 3.1.1, 3.2.1, and 3.3.1. General information about the Group Policy server, Group Policy client, and Administrative tool ADMs for Group Policy follows:
Server Abstract Data Model: The Group Policy server implements AD DS for the storage of managed generic objects known as GPOs, along with the policy information that affects these objects. However, the Group Policy server itself does not introduce any specific ADM elements. Rather, the Group Policy server maintains state in two conceptual stores: an Active Directory data store and a domain-based Group Policy file share data store that is accessible through a file access protocol.

For additional information about the Group Policy server ADM, see [MS-GPOL] section 3.1.1.
Client Abstract Data Model: The Group Policy client ADM is described in [MS-GPOL] section 3.2.1.
Administrative Tool Abstract Data Model: The Administrative tool ADM is specified in [MS-GPOL] section 3.3.1.
Note Extending the Administrative tool requires the use of the ADM.
