Can anyone help me with this? My WinXP and 17"PB are connected via an AEBS. I've had trouble trying to network them both together, but seemed to have managed to get some sort of connection. The DSL is shared via the LAN on the Airport, so the PC gets a good connection, but neither computer recognizes each other. The funny thing is that I can ping the PB from the PC, but not the other way around. What is the deal?
