Timeout issue on LAN Multiplayer with Age of Empires II: The Conquerors on Windows 7

I'm attempting to connect to me and my brother's computer to play our old Age of Empires II The conquerors through our LAN connection.

The thing is sometimes it works, sometimes it doesn't. Almost always it doesn't.

We are always able to see each others games, but when either one of us clicks "join" and the loading screen comes up, we wait 15 seconds and then see a pop-up sending us back to the main page saying "Unable to connect"

We have tried multiple things to fix this,

  1. Set the compatibility of the .exe file to Windows Vista (Service Pack III) even though we both have Windows 7

  2. Turned off our firewalls

  3. Direct Connect through Static IP addresses.

  4. Direct Connect through Hamatchi VPN tunnels.

None of these have changed anything. It still supposedly "times out" with the pop up message "Unable to Connect"

Any help would be greatly appreciated!! Sorry if it's a re-post, I've spent a lot of time looking for the solution and have been unsuccessful.
