6.1.5.2 Domain Naming Master FSMO Role

The Domain Naming Master FSMO role owner is the DC responsible for making changes to the forest-wide domain name space of the directory in the Partitions container. This DC is the only one that can add or remove a domain or application NC from the directory. It can also add or remove cross references to domains in external directories. Only the Domain Naming Master FSMO role owner can write to the Partitions container or its children. There is only one Domain Naming Master FSMO role per forest.
