Our network has one physical and one virtual Domain Controller (Windows 2008 R2 each)
The physical server and the virtual server host are both in the same rack in the server room.
It was brought up in one of our meetings that we should have an off-site domain controller as a hedge against a disaster that took out the server rack.
I have an unused server at my home and a very fast Comcast connection. Is there any value in either promoting the server or creating a VM to promote...and then use SonicWall SSL VPN as the link?
