Hello everyone, I am beginning to test my first multiplayer xna game, but I cannot seem to get a network session working. I am now using the ClientServer sample, setting my xbox as the server and trying to connect from my pc. Creating and finding the session is fine, but once I pass any AvailableNetworkSession (returned from NetworkSession.Find) to NetworkSession.Join I get the error: "Session not found. It may have ended, or there may be no network connectivity between the local machine and session host." I searched the error, but only got two forum links: http://forums.xna.com/forums/t/33349.aspx http://forums.xna.com/forums/t/30679.aspx I can provide as much info about my network as possible, but it is a simple setup so I don't know why it won't work. I doubt the problem is using a local pc gamer, since one of the earlier users reported neither systemlink or playermatch working. The other user said playermatch wasn't working on some xna examples, but DID work for NetRumble (unfortunately after this the TC vowed to do more research and did no follow-up posting). I am using the ClientServer example with no modifications, trying to create a SystemLink match, and having absolutely no luck. I hope someone can shed some light on this, as I need a way to test networked games. Any advice would be helpful, thank you!

I think I have it working now! I managed to not notice internet connection sharing was enabled, turning it off made the error stop appearing.

Hello

I am having a similar problem.  I think the problem might be that I am using a VPN (hamachi) for my network, as the person I am trying to test with is not at the same house as me.  I do not have internet connection sharing enabled, but I still get the error message.  Just as with you, NetworkSession.Find works great, but NetworkSession.Join fails with the exception.  Does anyone have any other suggestions what might be causing the problem?
