John, I'm confused about your deployment of "Open Access network using WPA/TKIP". WPA/TKIP would more likely be used in 802.1x access. Perhaps you can provide more details on your configs.
Using Wireshark or some other sniffer on one of the laptops that works and one that doesn't might provide you with more info on the DHCP requests and responses.
