I'm having trouble setting up a home LAN/Network connection between two computers. Both computers are connected to a 4-port broadband router directly using ethernet cords. They both can connect to the internet fine with no connectivity problems, but they just can't seem to read each other. I would like to try to enable file sharing between the computers and most of all achieve LAN gaming abilities. The funny thing is that one game can do LAN in between the two computers but the rest can't pick up each other. I have done the Windows XP setup wizard for home/office network setup and I've tried about 10 million combinations between the two computers on setting it up and I've run out of ideas. Both of the computers are on Windows XP and have 100mb Ethernet LAN Cards on CAT-5 Ethernet cords. One computer has regular Windows Firewall while the other has Norton Internet Security. I've even disabled both of them and even tried to allow them to permit each other by allowing IP range access and opening up the ports for signals. I can ping/trace the computers between the two on both of them, which means they should be able to read each other, but when it comes to directly connecting they just don't seem to go through. If anyone has any ideas/suggestions/methods I would strongly appreciate it; thanks!
