Let me explain out scenario:
We have a totally virtualized live production system running all the production VMs in a Microsoft Failover cluster. The interesting VMs for this questions are the Main Domain Controller (SRV-DCA) & Secondary Domain Controller (SRV-DCB).
Now we would like to export/copy these two virtual machines onto a backup server so that we can run some tests on the DCs not on the production environment.
We tried to shutdown SRV-DCA and SRV-DCB on the live servers and did a normal Hyper-V export. Then when the export was ready, I imported the Exported DCs to the backup server using the Hyper-V Import (Register In-place (use existing unique-IDs) and started both VMs on the backup server. When both where started and I tried to open Active Directory users and computers, it was stating that the domain controller could not be found, also I tried to do a "netdom /query fsmo" and it stated that the domain controller could not be found or contacted.
Now what I don't understand is what might have happened during the exports because the VMs were turned off. what other way can I export/copy domain controllers so that I can then run tests on a backup server without giving me such problems?
