Locked out of Domain: trust relationship

[fritzleboo]

I have Windows 2008r2 hosting my domain on a virtual machine. The weird part is that a local username logs into the server housing the virtual machine which houses the domain controller. Since the virtual machine is powered down.. I can't get into the user account (.local) which has the virtual machine. So in stuck. I can get into the Windows Administrator acct on the local machine. Any idea on how I can get to this account?

Just to ensure I'm understanding this correctly: the 2008R2 is a physical server, which is hosting the DC as a vm?

The main machine is a Dell server running Windows Server 2012. The virtual server is on the desktop of a local account on that machine.. the account is called 'backup' and it connects to an elevated user on the local domain....
I can't get into the backup account. On the desktop of that account is the VM. The VM needs to be turned on and run windows server 2008 r2. I can only get on a local admin account on the 2012 server and can't login to that backup account!?! The domain controller is on that virtual machine housed on the backup user desktop.

Did you make the 2012 server a member of the domain?

If all the AD controllers are powered down then you shouldn't be having a trust relationship error. The way to get around a trust relationship issue is to disconnect the computer from the network so it uses cached credentials.

Just an FYI, but this is a badly designed setup.
