Wireless Zero Configuration

Available in Windows XP and Windows Server 2003, Wireless Zero Configuration is a feature used to dynamically select the wireless network to which to attempt connection, based either on your preferences or on default settings. This includes automatically selecting and connecting to a more preferred wireless network when it becomes available. If none of the preferred wireless networks are found nearby, Wireless Auto Configuration configures the wireless adapter so that there is no accidental connection until the wireless client roams within the range of a preferred network.
