problemas con la conexion LAN

[amma87]

hola a todos soy nuevo en esto queria saber si alguien me puede ayudar

tengo dos compus en casa conectadas en red dentro de un mismo grupo de trabajo, puedo pinguear una con otra pero cuando intento jugar con mi hermano al Call of duty 4 , en la opcion de "DEDICATED" coloco LAN automaticamente el juego se cierra y me tira los siguientes errores.Si alguien sabe como solucionar esto por favor que me ayude.Espero haber sido claro , si no se entiende mi pregunta tratare de explicarla mejor.

Gracias.Saludos
