Chapter 10: Naming Services

Overview

Naming Services occupy an important supporting role in a technical infrastructure. They are relied upon by both applications and other services to provide a convenient way to reference other computers. A naming service needs to be one of the first services implemented in a technical infrastructure.

Naming services were introduced in Chapter 2, Elements of a Technical Infrastructure . They are necessary so that a textual or friendly name humans can understand, can be translated into numbers (address) a computer can understand. In particular, the idea of a set of computers whose task it is to maintain a list of name to address mappings and provide a look up service was used to illustrate a naming service.

The naming services that concern us in a Windows NT based technical infrastructure are the NetBIOS Naming Service implemented by Microsoft called WINS (Windows Internet Naming Service) and DNS (Distributed Naming Service), used in the internet community as a host name service.

Until recently, NetBIOS naming services were confined to a Microsoft environment and DNS to the internet or UNIX based environment. The need to reference resources between the two environments has given rise to the need to integrate the process of name resolution. The Microsoft environment is evolving towards exclusive use of DNS and as it does, reducing its dependence on a NetBIOS naming service. For some time, it will be necessary to provide both services, as well as a level of integration between them.
