Description: a single-level network with static IP addresses, all computers are connected to a single Cisco 2950 switch, there is no firewall, and firewalls are disabled on the XP sp3 computers. The DNS server is in the same VLAN, and telnet traces without any problems.
The h3wog.exe file, version 3.2.0.0, is used. The game directory has been copied from one USB drive to all computers. In the local version, everyone plays without any problems or glitches, but when trying to create a game using the TCP/IP protocol, the following happens: one of the players creates a session, it is visible, and it even seems to connect, but the map creator does not see the connected clients, and when trying to start the game, a message appears saying that at least two players are needed to start. On the client machine, when connecting to the session, there is no option to choose a castle color or hero, and the "Start" button is not active; the chat does not work.
If you create a session, connect all the other players to it, and then disconnect yourself, when you reconnect, you will eventually see all the other players, but when you try to start the game, after about a 10-minute timeout, a data transfer error occurs.
Where should I start looking for the problem?
