What Qualifies a Domain Controller on the Network?
Every machine that is a domain controller for the domain MIDEARTH has to register the NetBIOS
group name MIDEARTH<1C> with the WINS server and/or by broadcast on the local network.
The PDC also registers the unique NetBIOS name MIDEARTH<1B> with the WINS server.
The name type <1B> name is normally reserved for the Domain Master Browser (DMB), a role
that has nothing to do with anything related to authentication, but the Microsoft domain
implementation requires the DMB to be on the same machine as the PDC.
Where a WINS server is not used, broadcast name registrations alone must suffice. Refer to
for more information regarding TCP/IP network protocols and how SMB/CIFS names are handled.
