I have been trying to upgrade some IBM T20 laptops running Win XP SP1 to support PEAP. The laptops have been operating without security and had the ACU loaded. Once the ACU is upgraded to 6.0, drivers to 8.30 and firmware to 5.20. from CCO, the setup works fine with no additonal config change. However, as soon as PEAP is enabled in Win XP and the PEAP profile is selected in ACU, the PC will blue screen soon after the user has been authenticated.
The blue screen shows an 'IRQ_not_Equal_to_Or_Less_Than' error message.
Windows XP, HP laptops, Cisco Aironet 350 and D-Link WLAN-adapters, 1100 Aironet AP, EAP-TLS (MS Radius), EAP-TTLS (SecureW2, Odyssey Radius), Cisco VPN Clients 3.6.3, 4.0.1, 4.0.2 => in all combinations bluescreens first exist and then disappear when Deterministic Network Enhancer is disabled. After that 802.1x works fine but no vpn.
Question: How to provide 802.1x with these products wlan security inside company wlans and with the same wlan-adapters also support airport & other public wlans for vpn connections? Without giving users too much permissions.
"We" found a solution: the vpn client must first be uninstalled manually by cleaning all the cisco & dne drivers, registry settings etc. After that the client can be re-installed and things start to work: both 802.1x and vpn can now be enabled on the wlan adapter, no bluescreens or other problems any more.
Special thanks to Cisco TAC, Marco Castro, who did an excellent job by finding us the right solution!
