Experts,

My company was sold and we are migrating off their network to a new one.

I have created a new AD Forest (Win2008R2) in the same subnet and our servers and desktops have migrated successfully. This exists happily in the old subnet along with the old company's live AD domain we moved away from. With a little tweaking we have accounts and shares working pretty well. We now have to switch subnets away from them to a NAT one, 192.168.100.xxx. I'd like to test this move in advance.


I'd like to test in advance by moving a "disposable" DC that will be wiped after the test to a different physical network and use the NAT network. I'd bring over a couple "disposable" workstations and a "disposable" server. This will be using a different WAN connection and would be connected to the internet separately from the old network.

I took my "disposable" DC over to the NAT network but DNS and DHCP will not start. I assume because it doesn't see the GC, have the FSMO roles, or other needed pieces.

Is there an outline of steps I would want to perform to do this test, without taking down the two live DCs on the old subnet before I'm ready?
