So I asked the Below question in the server 2012 general forum but i am sure it is the wrong forum so I though I would ask it here in the hyper-v forum .
So I have one DC in my environment that I would like to upgrade from Windows Server 2012 to Windows Server 2012 r2. I thought before I upgrade the production server I would convert it to a Hyper-V virtual machine and preform the upgrade on a machine that can be deleted if the upgrade goes horribly wrong. We use Symantec Backup Exec 2014 to backup and restore. So I was able to restore to a virtual machine, the machine powers on, I was unable to open any of the ADDS administration consoles until I added a Microsoft loop back legacy NIC. To make matters worse when I try to run the in place upgrade from Windows Server 2012 to Windows Server 2012 r2 I receive and error asking me to first run ADPREP /FORESTPREP and /DOMAINPREP. Unfortunately when I run either one of these commands I receive an error saying that that ADPREP can find the DNS name for the domain or forest. So my question is how do I restore an ADDS server to a virtual machine and bring up all the services so that it functions in the capacity that the physical machine was functioning but in a closed environment. Thanks for your time and consideration of my inquiry.
Best regards,
