The third partition is the Domain naming context, which is replicated to all of the domain controllers that host a particular domain.

Examples include the DomainDnsZones partition, which is replicated across all AD integrated DNS servers in the same domain, and ForestDnsZones, which is replicated across all AD integrated DNS servers in the forest. This capability gives administrators much more flexibility over how they can store and replicate the data that is contained in Active Directory. If you need to replicate a certain set of data to only two different sites, for example, you can create an application partition that will only replicate the data to the domain controllers in those two sites rather than replicating the data to additional DCs that have ...
