GameRanger works with HotA, just rename h3hota.exe to "Heroes3.exe" and point this file in GameRanger's settings. The question is - why it doesn't work for everybody. As I stated before, we managed to connect 3 of 5 players. 2 can't join no matter what we do.

@Sav
The firewalls on our PCs are disabled, it is the first thing that everybody who wants to play H3 multiplayer does. Also, we all have this DPWSOCKX.DLL in H3 directory, so it will not help.

Any other suggestions?
