Make an existing domain a child of a new domain tree

[-glenn-]

Sorry if this has already been asked here (it probably has been but I
can't find it).

I have a newly built Win2k Server. The network this server is on has no
AD servers. The server had AD installed on it in a new forest, in a new
tree, and in a new domain (foo.example.com).

If I bring up another Win2k Server and put AD on it in a new forest, a
new tree, and in a new domain (example.com) will I (easily) be able to
make the existing foo.example.com domain a child domain of the
example.com domain tree using ADMT or some other tool?

Thanks!

You would have to to use ADMT to migrate any users from foo.example.com to
domain example.com. IF the domain is newly created and you have few users
and few workstaions then it would be eaiser to just demote back to stand
alone server and create promote to domain example.com

You make the child - parent relationship during dcpromo.
to answer your question yes and no. You *can* do it but it is not easy.

If you don't add the child domain to the parent domain during dcpromo on
that child domain, *that* child domain can not be added to the parent, but
you can set up a third domain as a child domain of your existing parent
domain and use ADMT to migrate users from the separate domain.

Example:

Parent domain = mydomain.com
Child domain = Child.mydomain.com

Second domain (orphaned, new forest, new tree) = mycompany.com

Since you did not create "mycompany.com" as a child domain of "mydomain.com"
during dcpromo, you would have to create a third domain and add it as a
child domain of mydomain.com during dcpromo (Child.mydomain.com) and use
ADMT to migrate users from "mycompany.com" to "Child.mydomain.com".

When you choose a name for the new domain in a new forest and new tree,
don't use the same name as the final name you want your child domain to
have. ADMT needs to have a trust established between the two domains and you
can't create a trust between two domains with the same name.
