I want to share folders between my two computers A and B. Would also like to share internet thru ICS. Both the computers have windows 7. This is the setup - One direct lan connection from router to A, then another lan on A is connected to a switch. B is also connected to a switch. On A, I have allowed other network users to connect thru this computers connection (for the lan card which is connected to the router). The other lan connected to the switch remains unidentified, in fact it gets APIPA with IP as 169.254.82.6. What am I doing wrong here pls ?
