Marlon,
Further to what Andrei stated, DNS - if AD integrated - is indeed stored in
the Domain Partition, or Naming Context. That much is clear.
But what are these Partitions? Active Directory is chopped up into three
pieces - the Schema Partition, the Configuration Partition and the Domain
Partition. The first two Partitions, or Naming Contexts, are replicated to
all Domain Controllers in the entire Forest. The Domain NC, however, is
replicated only to those DCs in that specific Domain. So, if you have an
empty Root Forest and three sub-domain ( for a total of four domains ) you
would have the Schema NC and the Configuration NC being replicated to all
Domain Controllers in the entire Forest ( so, to the DCs in the empty root
and to the DCs in each of the three sub-domains ). However, the Domain
Partition ( and there would be four of them ) only is replicated to the DCs
in that domain. I repeated for emphasis. The empty root ( yourdomain.com )
would have a Domain NC; sub1.yourdomain.com would have another Domain NC;
sub2.yourdomain.com would have another Domain NC and finally
sub3.yourdomain.com would have another Domain NC.
HTH,
Cary
