I have a laptop running Server 2008 and Hyper-V. I have created a virtual machine that is also running Server 2008, that I used
dcpromo to create as a domain controller. I disabled IPv6 because I had no idea how to enter a default address, and I just wanted to make a standalone MOSS dev environment. I have tried every combination of creating a virtual network on the host and then connecting to that in the VM, but I can't get the VM to communicate with the host and vice versa. No pinging, no copy and paste, nothing.
To update: My VM (which is its own DC) currently does not have a static IP. When I set the IP to static, I could not find anything that would let it talk to the host machine.
