Both machines mentioned are VMs (xenserver)
I have a dc server that has failed. (Raid failure and corrupted VM) It was also a DNS server and had DFRS namespace function.
There is a second server that has all the roles and is a global catalog.
I do have a vm image (3-4 days old) of the failed server.
1 - Would there be any benefit to boot the image and run dcpromo to remove it from the domain? Or would there be AD contamination?
2 - I can live without the DFRS for a few days
3 - If I do not do dcpromo on the image, how do I make sure that the server is removed from the domain?
4 - What about DNS?
