Windows XP caches credentials for PEAP.  If you want it to reprompt,
you'll need to delete a registry key
(HKCU\Software\Microsoft\Eapol\UserEapInfo).  See
http://support.microsoft.com/kb/823731 for more info.

Vista has the ability to control caching of credentials (i.e., you can
tell it not to do so).
