A number of years ago I was regularily hosting games on my computer but since I bought a newer (Windows 7) computer I have been unable to do so. I recently borrowed a computer (Windows XP) and have installed the H&D2 game but as yet have not been able to host (my game does not show up on listing). As recommended in a few posts, I have turned off the firewall, and think I have opened ports 11001 to 11004 as well as 27900 and 28900 (both TCP and UDP).

Am I missing something? Any help would be greatly appreciated.

The master server is no longer operational. You need to add the server to your server list manually or use a 3rd party server browser.
