Child domains and sites

[Guest]

Probably a stupid question but.............

Do child domains also have to be a site in the root domain

What gets replicated between a child and the root domain?

Thanx in advanc

Hi drumdave, The Configuration Naming Context and The Schema context are
replicated.

Sites Objects are global for all domains within a domain tree. This means if
you have a site called New-York and an assigned subnet ex 10.11.1.1 Domain
Controllers within the particular subnet will be assigned to Site New-York
no matter what witch domain they operate in.

Sites are located in The Configuration Naming Context

DrumDave,

Not a stupid question! To answer: No, child domains do not *necessarily*
have to be in the same Site as the Root - but they can be!

What gets replicated? The Schema Naming Context and the Configuration
Naming Context are replicated to each and every Domain Controller in the
entire Forest. However, the Domain Naming Context is replicated ONLY to
the DCs in that particular Domain. So, all of the DCs in the root domain
would get that particular Domain NC while all of the DCs in the child domain
would get that particular Domain NC.

HTH,

Cary

Thanks for the replies.

Just so i understand this fully. I have a couple of question

I have "root.local" domain and want to add a child domain under this called "child.root.local"

After setting this up, do i have to create a site for this child domain in sites and services at the root for the replication to take place ( If any at all is needed)

Also when i dcpromo the child domain should i have a secondry zone of the root already running at the child domain? Microsoft says you should delegate at the root before i dcpromo the child domain.

I hope this is all making sense.

Thanx agai

No. All servers and clients may be in the same site as any other domain's
servers and clients. Sites and domains do not necessarily have anything at
all to do with each other. Think of it this way ...

Forests and domains are logical constructs that have to do with locating
objects in an LDAP namespace. IOW - they are hierarchical.

Sites are topgraphical constructs objects that are related to network
topology and control how domain controllers replicate with each others and
how clients access resources closest to them.

A domain may span many sites ... a site may have members of many domains
....

Also when i dcpromo the child domain should i have a secondry zone of the

root already running at the child domain? Microsoft says you should delegate
at the root before i dcpromo the child domain.

This all depends upon the location of the domain conrollers and servers in
the new domain and who you would like administering them. If your
installation is fairly simple and the existing DNS is running dynamic zones,
you can run DCPROMO and the child domain will be created automatically on
your DNS server for you. If you wish a different DNS server to host the
zone information for a new domain, then perform the delegation to that
server - then run DCPROMO.
