I have a production windows 2008 R2 with a major production application installed that I cloned for purpose of creating a test environment. I used the built-in backup\imaging from windows 2008 R2 (works same in windows7) and restored it to a desktop PC.
As soon the desktop was connected to the network the production machine lost domain trust relationship (by the way I didn't connect it to the network-somebody else did by mistake).
I know changing the computer name is not sufficient as there is a SID that I think should be changed. Can I use windows SYSPREP on the cloned desktop in this situation (i think sysprep is typically for pre-imaging but don't want to do this on production system as I was able to get production running again after deleting & re-joining the domain).
I heard about a program called NewSid but it is retired.
Since I do need this test desktop to be on our network how can safely join it to the domain without causing problems again for the production original?
This tutorial will walk an individual through the steps necessary to join and promote the first Windows Server 2012 domain controller into an Active Directory environment running on Windows Server 2008.
