Assigning DNS Names to Create a Domain Hierarchy

Assigning DNS Names to Create a Domain Hierarchy: "Because DNS is the predominant name system on the Internet, DNS names are globally recognized and have well-known registration authorities. Active Directory clients requesting to log on to the network query DNS to locate domain controllers.

In Windows NT 4.0, the domain locator was based on the network basic input/output system (NetBIOS) Name System (NBNS), and domains were identified with NetBIOS names The server-based component of NBNS is called the Windows Internet Name Service (WINS) server. NetBIOS names are simple, single-part names, and the NetBIOS namespace cannot be partitioned. In contrast, DNS names are hierarchical, and the DNS namespace can be partitioned along the lines of the hierarchy."
