I have a server application running in an XP Mode virtual machine in Virtual PC. The host system is Windows 7. I can't seem to connect a client running on the host system to this server (over a TCP connection), there is so response. I tried setting up the network connection in the VM as both NAT and Internal (restarting the VM each time), but there is no response from the VM (client never connects and ping reports that its unreachable). I tried turning off both firewalls as well. Any advice?
