By extension, the Active Directory can seamlessly extend the view of the local network out to the Internet. And this extensible view need not be just of the Internet. The Active Directory gives users, managers, and administrators a familiar, orderly, and scalable view of network connections, regardless of scale. The heart of directory services is the ability to locate, name, and communicate with all of its network resources. In a dynamic network at a growing company, this is challenging because network resources are constantly changing.
Networks are highly dynamic.
DNS has to perform this translator service because the network and its users speak different languages. Administrators build networks by organizing objects, while the system negotiates the network using IP addresses. This lets it manage network resources consistently with Internet conventions, while at the same time allowing a name-based, logical view of the network for users. The Active Directory locates and maps network resources not just by name, but also by its object's attributes. In fact, to the Active Directory, an object is its set of attributes.
