replication between domains

[srinivas Acharya]

Hi All,
As for as knowladge goes, replication happens within domain
only. There is nothing like replication between domains. is
that right?. is there any replication happening between sub
domains of a same domain tree?. is there any replication
happening between domain trees?.


Please comment.

In the forest some parts of AD are replicated between domains,
configuration and schema.

the full domain data replication occurs only between the DC's in the
same domain

Hi,
Thanks for replying.

In your above statement, can you just tell me domain means
domain tree or subdomain. I wanted to know whether you are
refering to DC of subdomain or domain controllers of domain
tree?..

Srinivas,

I might jump in here for a second.

In WIN2000 Active Directory there are three Partitions, or Naming Contexts
(NC), that are replicated. The first NC is the Schema NC. The Schema NC is
replicated to all Domain Controllers in the entire forest. The second NC is
the Configuration NC. Like the Schema NC, the Configuration NC is
replicated to all Domain Controllers in the entire forest. The third and
final NC is the Domain NC. The Domain NC is replicated to all Domain
Controllers in that particular domain.

So, let's take a look at an example.

Let's say that you have an enterprise that has an empty root and three child
domains. The empty root is wazup.local. The three child domains are
hr.wazup.local, finance.wazup.local and general.wazup.local. In each of
these four domains are two Domain Controllers. In the root domain (
wazup.local ) the Domain Controllers are named DC01 and DC02; in the hr
sub-domain the Domain Controllers are called DC11 and DC12; in the finance
sub-domain the Domain Controllers are named DC21 and DC22; and finally in
the general child domain the Domain Controllers are named DC31 and DC32.

The Schema Partition ( aka Schema NC ) will replicate to all eight Domain
Controllers ( DC01 and DC02; DC11 and DC12; DC21 and DC22; and DC31 and
DC32 ). Same goes for the Configuration Partition.

Now, this is where it gets interesting. The Domain Partition for
wazup.local will replicate only to the Domain Controllers in that domain -
namely, between DC01 and DC02. The Domain Partition for hr.wazup.local will
replicate only to the Domain Controllers in that domain - namely, between
DC11 and DC12. The Domain Partition for finance.wazup.local will replicate
only to the Domain Controllers in that domain - namely, between DC21 and
DC22. As expected, the Domain Partition for general.wazup.local will
replicate only to the Domain Controllers in that domain - namely, between
DC31 and DC32.

I hope that this helps to clarify things a bit.

Great answer Cary!!!

....And that's why Global Catalog (GC) servers come into things... Global
Catalog servers hold a partial replica of all domain partitions in the
forest (the most common attributes). This enables child domains to have
immediate info. of, for example, a user in a parent domain -not all the
info. but enough to process a logon request, etc.

Thank you, Paul.

I intentionally left off the Global Catalog Server part so as to avoid too
much information at one time ( and to leave it to someone else to possibly
ask or add ).
