When the DFS server is started:
It MUST notify the SMB server for reasons as specified in [MS-CIFS] section 220.127.116.11 and [MS-SMB2] section 18.104.22.168. The exact means of how this is accomplished is outside the scope of this specification.
It MUST initialize HomeDomain with the domain name of the domain to which it is joined, if any.
It MUST initialize DFSNamespaceList to the list of domain-based and stand-alone DFS namespaces that it hosts. This list can be obtained from DFS metadata (as specified in [MS-DFSNM]), a configuration file, a configuration store, or from other implementation-defined means.
