I desperately need to run Windows Server 2012 R2 Terminal Services on a standalone machine. To this end I've set up a Terminal Server with it's own license manager and installed 8 licenses. When I'm connected to our domain it works great, but once I remove the server from the domain by simply unplugging the network cable, it refuses connections from any MSTSC, even running it on the server itself.
I've read a lot on this and it appears that Microsoft has intentionally put a requirement in place that demands the Terminal Server be on a network with an active domain controller. So, my question is this:
Would it be possible to run a domain controller on a Hyper-V instance on the Terminal Server? I have 32 GB of RAM and 8-core processor on the server, so performance won't be an issue. Also, would Windows Server 2012 R2 Essentials be enough to get this up and running in the Hyper-V instance?
A speedy reply would be GREATLY appreciated as I'm under a severe time crunch to get this working.
