Is this on XBL or Local?



If on XBL, you NAT settings are messed up. You can fix them locally or through your ISP if you have a router.



If on Local, well there shouldn't be a problem so I can't help you here.xbox wont let me connect to freinds even ...
Thanks for your reply,



It is on Xbox live. As for the NAT settings, do i have to do anything on the xbox, or go into the router through the pc. I dont think its to do with the pc because the other two xboxs connect fine ??



Many thanks

Luke ps, sorry im very dumb when it comes to networks :)
It could be your router settings, you have to log in to your router and fix it from there.
it could very well be an induvidial 360 that's messed up; they all have unique IP's
