We have a several Cisco 4400 wireless controllers and a Cisco WLC, ACS server. Access points are Cisco LWAP 1242. Security is PEAP TKIP ms-chap. Machine authentication.
Settings are pushed out through group policy. A new user can log on to a laptop (without cached credentials) and get all their network settings....most of the time. Randomly we have laptops that after being restarted, receive "yourdomain.com is not available" error message. The laptops will work fine for weeks and then random laptops start to get this error. If we wire them into the network, they logon fine. Shutdown, unplug, and the wireless works fine again.
