AD Child domain problem

[Guest]

I had a problem when we migrated one of our NT 4.0 Domains to a new 2000 AD
Child domain. The first attempt failed due to some rogue settings on the dc
that were missed. We rolled back to NT 4.0, but had to force the dcpromo. I
removed the information from sites and services and reran the upgrade after
fixing the settings. It appeared to run fine and the child domain is still
working well as a 2000 AD domain. It thinks it is a child of my root domain
and all. The problem lies with the parent domain. It doesn't have any
record of the child domain in the tree structure. It sees it as an external
domain. I need to make it realize that the domain is a child. How can I do
this with out trying to undo the upgrade since the child domain is
functioning?

Then you probably created the 'child' as a NEW Forest and there
is no way to really migrated it directly into the existing forest.

You must either play with MANUAL trusts, or you must re-install
the child domain and migrate or re-create all of the users and other
objects.

You cannot.

MAYBE you just messed up the DNS zones, but it really sounds like
you installed a new Forest.

Go run DCDiag on DCs from each domain and make sure whether
the "Schema Master" (and Domain Naming Master) are the SAME
DC, or different.

These (two) are PER FOREST so if you have multiple you have
multiple forests.
