The same setup has been working for 3 days. All of sudden, the user cannot authenticate. The user doesnt get prompted to enter username/domain when connecting to the wifi lan. What follows is the complete log of the error. There has been no changes to my setup. I am using a cisco 4400 controller and 1 LWAP access point by cicso. It connects to my radius server based on windows 2003
Please, any input in the matter is hjghly appreciated. I have been fighting with this for a few days and cannot get it resolved. Microsft knowledge base articles have not helped me any.
Server: Windows Server 2003 x64 SP1 or R2 Client: Windows XP Pro SP2 From time to time some of my XP SP2 clients fail to authenticate with IAS and thus end up working without WLAN. This is what I get in System log:
