Wireless zero config service in winxp

Another example that proves Privacy and Security can not stay along with Convenience, the wireless zero config service in window xp. With this service turn on, an xp machine will automatically search for network from its preferred network list, which was build in the past which the machine used to connect to the internet. To find this network, the machine will periodically send out prone request that with SSID from teh preferred list in order to try connect the the network. The problem is, if someone sniffing and catch this wi-fi packet, he would know all these SSID, which is not cool at all.

Yeah, it is true that the wirelss zero configure brought convenience that it helps a user to reconnect to the internet automatically; however, it can also expose all the SSID to the outside world. It would be better to turn this service off.

Download this update from microsoft to turn it off: Wireless Client Update for Windows XP with Service Pack 2
