Scenario is a developer build out in VirtualBox. I am looking to combine the DC with NAT (2 NICs, one internal and one NAT) running server core 2012. A key goal is to hide the (internal) DEV domain from the outside world while still allowing any DEV VMs on the internal domain access to e.g. Windows Update.
Is this as simple as adding the NICs to the 2012 VM, installing the OS and then following one of the tutorials for creating a domain controller? Are there any steps I should take to prevent other physical hosts from seeing the DEV domain?
Thanks in advance for any insights, suggestions, etc.
