   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:
