Active Directory Split
I'm wondering if there's a way to take a server from a pre-existing domain, establish it as a DC and then move it to a new business and not have sync problems after 90 days (tombstone'd domain). Is there a procedure for this at all?

This is what is happening. Company B is purchasing part of Company A. Company A has a pre-existing domain that has a couple servers in it that Company B is purchasing. My question is (and I'm doubtful this is even possible) can I keep the domain intact and move the servers that are being purchased while cutting communication with the original domain, and create kind of a "clone" domain. If this makes sense.
If I understand correctly, you want to take a DC from an existing domain and use it to run another, new independent domain with the same name. You want to 'clone' your domain.
Technically, once the DCs are seperated permanently, you could perform a metadata cleanup on each server to remove traces of the other server from it's copy of the database. Then they wouldn't be aware of the split, and replication issues would be negated.
This explains how to perform a metadata cleanup along with a few other checks: http://www.petri.co.il/delete_failed_dcs_from_ad.htm
You would then have to ensure DNS is all correct, and clean up AD in the new site so that old machines/users don't exist. I sue there would be other problems, especially if your running Exchange.
Not sure why you would want to do this though! Maybe I've misunderstood your question :)

If the servers that they are buying are member servers then yes it is possible. You would just join them to the new domain.
If they are domain controllers then no you won't be able to move them into company B.
Not sure if that is what you are looking for.
Another option is to migrate the objects from companyA to companyB. That would take some planning and a trust. You could use a tool like Active directory migration tool for that.

What type of servers are those that being purchased and be removed from the existing domain? In my opinion, any member sever can be moved to any domain as long as you follow the configuration requirements. There's no reson to move the existing domain unless you plan to retain the name and continue to run those servers in that domain. What you call split domain is probably you want to move part pa the existing domain over and leave the rest remain. It possible if the moved portion has a DC as well as the remaining portion has a DC and these portions have no physical connection meaning cannot see each other. Otherwise you would have duplicate names etc. Even if they rull not be connected, you you still have to do cleaning on both portion of the splited domain ensure that the moved option does not exist in the remaining one and vice versa. Plus in that case, you also need to seize FSMO in at least one of the splited domain depending on which one has the domain and forest infrastructure. But this is just too odd and don't wish to recommend that path.

or are you just moving the DC from domainA to the physical location of domainB but still have connectivity back to the original domain?
