Active Directory Partitions List in Windows 2003 and 2008 Servers

By WireINPUT -
Active Directory data is logically partitioned so that each domain controller does not store all objects in the directory. Each directory partition, also called a naming context, contains objects of a particular scope and purpose. Below are the three major Active Directory partitions described:-
·         Schema Partition defines the object classes and their attributes for the entire directory. The configuration is replicated to every domain controller in the forest.
·         Domain Partition contains all the objects stored in a domain, including users, groups, computers, and Group Policy containers (GPCs). This partition information is replicated to all domain controllers within a domain, but not to domain controllers in other domains.
·         Configuration Partition contains objects that represent the logical structure of the forest, domains, as well as the physical topology, including sites, subnets, and services.
·         Application Directory Partition replicates directory partition only to specific domain controllers. The KCC (Knowledge Consistency Checker) is responsible for generating and maintaining replication topology. Objects stored in Application directory partition are not replicated to the Global Catalog.
