802.1x in wired environment

Hey Guys,

Do you guys know of a way to disable the caching of credentials that the
802.1x client does in Windows XP SP2?? I am a consultant testing 802.1x for
my client and I am not part of their domain. However, when I connect to an
802.1x configured port (Cisco Catalyst 3750), I do not get prompted for
authentication as I've authenticated before.

Thoughts??
