3.2.1 Abstract Data Model

  • Article

This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The organization is provided to explain how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document. The following state MUST be maintained at the DFS Server:

HomeDomain: Applicable only for a computer joined to a domain. MUST be the name of a domain to which the computer is joined. Maintained both in NetBIOS and fully qualified domain name forms. This is used to access the DFS metadata of a domain-based DFS namespace hosted by the server.

DFSNamespaceList: MUST be a list of domain-based and stand-alone DFS root targets hosted by the server. Used while processing DFS referral requests from DFS clients.

DFSMetadataCache: Cache that MUST contain the DFS metadata of DFS namespaces for which the server is a root target. The cache MUST be maintained as specified in [MS-DFSNM] section 3.1.
