Patch required if running Windows XP and WPA on an AEBS
If you have OS 10.3.x and have upgraded your AEBS firmware to 5.2, then you can now use WPA (Wi-Fi Protected Access) which is a more secure wireless network encryption than WEP.
If you are running XP SP2 then the patch is included with SP2.
If you have wireless XP SP1 PC's on your network, then you will need a patch for them.
