I have been obsessing getting back into the old Dune 2000. Goal is to LAN just 2 machines in my house to play. I have launched cnc as a LAN config and the 2 computers "connect." When we click "I'm Ready," the screen goes black and we get our hopes up as it appears to try and launch. A little Dune box comes up counting down to connect. At the end of the 20 second countdown it says "Failed to connect. Reconnecting to Lobby" or something like that. Anyone have a possible solution? We are so close...
