!!! Overview
[{$pagename}], in [Microsoft Active Directory], is the first [AD DOMAIN] created in a [AD Forest], it is the root domain in the [AD DOMAIN] namespace [hierarchy]. ([Directory Partition Hierarchy])


In naming only, the topmost object of the [Configuration Directory Partition] is the child of the [{$pagename}] object in the [hierarchy]. 

The distinguished name of the [Configuration Directory Partition] (cn=configuration,dc=[{$pagename}] ) reflects this naming [hierarchy].

Although the distinguished name of the [Configuration Directory Partition] indicates that it is a child of the [{$pagename}] object, the [Configuration Directory Partition] is not physically part of the [{$pagename}] directory partition but is a separate directory [partition] that is replicated to all [Domain Controllers] in the [AD Forest]; in contrast to the [Configuration Directory Partition], the forest root domain directory partition is replicated to only domain controllers in that domain. 

Similarly, the topmost object in the [Schema Directory Partition] is the child of the [Configuration Directory Partition]. The distinguished name of the [Schema Directory Partition] (cn=schema,cn=configuration,dc= forestRootDomain ) shows the location of the schema to be within the forest root domain. Although the [Schema Directory Partition] is a child of the [Configuration Directory Partition], the [Schema Directory Partition] is not physically part of the [Configuration Directory Partition] nor part of the forest [Root Domain Directory Partition].
