I've searched and searched the internet and can't find a solution to my problem.
My brothers and I enjoy playing LAN games together on our local network. We've got a 'Netgear Super Wireless ADSL Router DG834GT' (includes modem) two desktops running XP and my laptop which I just installed 7 on. The two desktops play multiplayer together fine, either one hosting or joining, but my laptop is the problem. The results depend on the game, though I've only tried three so far.
BG2: Throne of Bhaal - Either desktop hosting I can get to the password page, but can't connect after that. With me hosting, the desktops can't get anywhere.
SW: Galactic Battlegrounds - Desktop hosting I can see the game but can't connect. When I'm hosting neither desktop can see.
SW Battlefront 2 - Desktop's hosting, I can connect and play fine. When I'm hosting the desktops can't see again.
I've tried disabling all firewalls, followed the instructions here
and am able to share files any which way I want, but just can't seem to play games. It's like my laptop's not sending the required information. We're all on the same workgroup, I've disabled UAC, I've checked the registry entries for restrictanonymous, disabled IPv6 on my laptop, but I can't work the problem out.
Btw, I previously had Vista and had similar problems but I could usually get it working by playing around with the settings mentioned above.
Any advice would be much appreciated. I've uploaded the saved info from running DxDiag if you need to refer to it.
