I have taken over a Hyper-V 2012 R2 server. It was originally configured to be part of a domain that is no longer accessible to the server; it must have been setup at another IT company location then moved onsite where it hosts other VMs on another LAN/Domain. The VMs are working ok but at the moment we don't have a way to manage the Hyper-V part.
When I try to remove the Hyper-V server from the non-reachable domain I am unable to. I know the local admin creds but not an admin cred for the domain. Using the local Admin account does not work in removing the server from the domain.
