I have MS IAS 2003 and Cisco 1200 IOS doing PEAP authentication. I have this working OK however, during the day the clients who have been associated lose their association mid-day. I finally replicated this! When I logged on as a local admin who is not in the MS group to allow wireless access, it broke all of the APs associated clients and sent them into a 0.0.0.0 Association processing state. Upon logging off the local admin user all clients re-authenticated and re-associated with the AP.
Does any one know how to correct this problem? Any help would be great.
