Need to break off 2 DC's into its own forest - HELP!

I have a Active Directory forest with one tree, and a single domain.

I have a remote office with two domain controllers for this domain.

This remote office is breaking away from my organization into its own company, and I need to figure out how to break them away.

My guess is that I will need to create a separate forest for these two domain controllers, and a new domain within that forest. Is that correct? If so, how do I go about doing this? Do I run dcpromo on one of the domain controllers in the remote office to create the new forest?

Any thoughts that anyone has will be highly appreciated. Thanks.

You are right about having to create a new forest and domain as they will independent from the old organization.
I would consider doing the separation like following:
-demote one of the remote office DCs and drop it to a workgroup
-dcpromo it creating the new remote office forest and domain
-use ADMT to migrate remote office objects (users, computers etc) from old domain to new
-demote the second DC, move it to the new domain and promote it to DC
-clean the old domain from remote office's migrated objects

ADMT (Active Directory Migration Tool) can be downloaded here:

hope this helps
