Question : Create 2003 AD replica test lab on virtual servers / different hardware

Problem: I need to merge 2 forests GAL’s using Microsoft Identity Integration server, this needs to be done in a test lab first.

Ok so I know I can import accounts and objects in to 2 replica forests using CSVDE but I really want all the full AD partitions to be there for a true representation. The tricky bit is the fact that I want to restore AD on to 2 virtual hosts, I can find documentation on how to restore to different hardware under Windows 2000 but nothing on 2003. Ideally I want all AD factors to be as close to the production systems as possible.

Answer : Create 2003 AD replica test lab on virtual servers / different hardware

Create the VM with all necessary services while it has network access to your production domain.
dcpromo it. Wait for replication.
Switch the VM to an internal network on the VM, do NEVER EVER bring it back in contact with your production domain again!
Remove the VM from your AD:

Seize the FSMO roles on the VM:

Transfer the Licensing server to the VM:
In AD Sites and Services, right-click "License Server" in the right pane, choose Properties, and move it to the new server.

To be able to transfer files between the VM and your production network (apart from using iso images or CDs):
* Install the MS Loopback NIC as additional NIC on the virtual server, give it an address different from your normal subnet; disable NetBIOS over TCP/IP on this NIC. Change the IP address on the VM accordingly.
* Bind the VM's NIC (or the virtual switch if you're using one) to the Loopback NIC.
* Transfer the files to a folder on the VS, map this folder from the VM using the loopback NIC.
