I should add that with Windows XP you can configure the wireless 
interface so that it will ONLY associate with preferred networks, that 
is one which you have configured  for access if you are using the 
Wireless Zero Configuration client. Also, if you have a recently 
purchased Access Point and client NIC cards then you can upgrade them to 
Wireless Protected Access (WPA) in either pre-shared key mode (for small 
networks without a Radius server) or in the case of Microsoft OS based 
networks EAP-TLS or PEAP MSCHAPv2 authentication. Using either method 
will assure you that you will not associate with and authenticate to an 
unintended Access Point. I have a paper submitted to SANS GIAC on the 
subject of WPA in Microsoft networks which you may find useful in your 
own project. Please let me know off list and I will forward you a draft.
