Advice on Active Directory Design

[James Reichner]

I need to ask a little advice. I currently work for lets say company A.
Company A used to own company B. Companies A & B are both owned now by
company C.

I am in the process of separating the systems. I have NT 4 experience but I
am a bit confused about this gets setup. The parent company is currently
not helping with this design or separation. I was hoping that there could
be some way that I could design AD to allow each controller to interoperate.

How can I get companies A and B to interoperate and possibly allow company C
to join later? Just keep in mind that company C is the parent.

Thanks in advance.

What are you doing? Upgrading the 3 companies to Win 2k? Upgrading the 3
companies to W 2k3? Are they already Win 2k or Win 2k3?

What do you want the final results to be? 1 forest, 1 tree and child
domains? 1 forest and 3 trees?

Hello, you have to find out if you want to share same domain name as the
follow:
a.company.local
b.company.local
c.company.local

if you want that structure you can easy begin with an empty root domain and
add the companies as child domains when that is necessary. How ever, if you
want to have total different names, you may want to setup a forest with a
couple of trust to each companies domain.

They will be new installs of Windows 2000 server but the parent already is
running Windows 2000 server.

I am not sure why the parent company is not including themselves in this
phase but....I guess The company that we used to own will still need access
to our email and terminal server. I am really not sure of the best way to
approach this and I was just looking for some suggestions.

One rule to follow is the parent must be created before the child. You can
not create the child domain and "add" the parent domain later. (Well you
can, but not without blowing away the child domain and recreating it.)

of course, if you want to use a shared name, the root domain must exist to
add child domains. may I didn't point this at my post sorry

Company C could be accessed over a WAN link and their company domain is
apollo.com.

What I was hoping to do is to design this for the future need of Company C
to access both Company A and B systems and data.

And there is another idea.....

Then have Company C (Apollo) join this forest later.....

I know the graphics are a bit confusing but then trust relationships can be
setup. Now that brings up another question, can members of a forest be
disjoined and then rejoined to a different forest?
