Hi guys ,
I am facing some problem with my Wireless solution .
My wireless soultion contains a WLC and 10-15 AP's.
1)I am using DNS methods for getting the WLC ip address for the AP's (mapping the FQDN
CISCO-LWAPP-CONTROLLER.aja.win.ml.com to the WLC ip address on the DNS server ).And this is working fine for me .
2)When i am trying to connect my laptop to the Wirless network i am getting the PC's MAC listed on the WLC and it is
trying to authenticate from the ACS as well
3)But i am seeing the ACS logs the following error :" NAS duplicated authentication attempt " and it keep on going .
I realy stuck here since i am not sure what is this meant by .So please help me out if some one
got this problem some where before .
Please go to ACS > System Configuration > Global Authentication Setup > Under PEAP uncheck "Enable Fast Reconnect:" option > Submit + Restart.
Please apply following Windows patch on WindowsXP SP2 clients, if you want to use Enable Fast reconnect option on ACS server.
Execute "WindowsXP-KB885453-x86-enu.exe" file in the zipped file.

Hi JG ,
I had applied the patch on my Laptop .
I seeing some changes on the ACS's logs now .
Before installing the patch it was continously failing saying "NAS duplicated authentication attempt "
I thing we have to get :"Re-key OK" also for the sucessfull authetication .That i am not seeing on the logs .
