I came across the following problem. I installed a Windows 2008 Core installation (no gui), with Hyper-V. To administrate this server you have to open the Hyper-V manager from a different computer. Then you can add virtual machines to the server.
After creating a new virtual machine and starting it, I was able to see the vm starting up in the preview window, but when I tried to open the virtual machine with the Virtual Machine Connection the operation timed out and I ended up with this error:
"Cannot Connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator."
After some netmon capturing I found the source of the problem. TCP port 2179 was not allowed inbound to the server. After enabling this port in the firewall the problem was solved.
