Network hosts and services are configured with DNS names so that they can be located in the network, and they are also configured with DNS servers that resolve the names of Active Directory domain controllers.

The host names of the computers in this network were managed through the use of a single HOSTS file located on a centrally administered server.

Each site that needed to resolve host names on the network downloaded this file.

The implementation of DNS — Berkeley Internet Name Domain (BIND) — was originally developed for the 4.3 BSD UNIX Operating System.

The Microsoft implementation of DNS became a part of the operating system in Microsoft Windows NT Server 4.0.
