Is the network connection in XP still "on" after the PC is shut down and thus potentially vulnerable 24/7? I'm on 3 PC network at home, and the 2 XP machines still show a green light, indicating that they are talking to the router via the NIC after the computers are shut down. The 3rd PC is a 98 machine, and when it shuts down, the network connection indication loses the green light.
