A THREAD FOR NEWCOMERS!

Please help with the multiplayer game. There is a local network (2x Windows 7 and 1x Windows XP with all updates and DirectX). All firewalls are disabled. There was a problem with the connection (IP address not found) - it was resolved by replacing dpwsockx.dll (4.8.0.400). Now everything connects without problems, and it works fine when playing with two players. But when playing with three players, problems arise when the second player finishes their turn (error when sending data). I tried it on "Heroes III: Armageddon's Blade" and "Heroes of Might and Magic III: Complete". There is no IP or MAC address conflict.
