NAS duplicated authentication attempt

[BERNHARD FIEGLMUELLER]

Hi

We are using peap with acs 3.2.

I often see the log message in the acs: NAS duplicated authentication attempt

but only at clients with integrated wlan cards. with xp ans sp2. with cisco cards no problem (with adu). is this a MS issue? if i reboot the notebook or disable the card and activate it after some time it workes fine.

does anybody have this issue and a better solution?

it seems that it is a ms issue:

Known Microsoft Problems

Due to a defect in the Microsoft PEAP supplicant provided in Windows XP Service Pack 2, the PEAP supplicant cannot reauthenticate successfully with Cisco Secure ACS. Microsoft case SRX040922603052 has been opened on this issue. Customers affected by this problem should open a case with Microsoft and reference this case ID. Microsoft has prepared hotfix KB885453, which resolves the issue.
