We are using Windows XP clients with WPA2 enterprise PEAP machine and user authentication (using windows supplicant, with the PEAP patch installed). We are using ACS 4.0.1 servers for authentication in a WDS environment.
The issue is sometimes we will see the laptop request authentication to the network once the user logs in. A yellow dialog box will appear in the lower right hand corner of the screen and request they reenter the username, password and domain. It does not happen often and most of the time this happens if for some reason the WLAN goes away, like a power outage, etc. But it does drive the users crazy and they drive me crazy about it.
Has anyone experianced this issue and know of why it is doing it and how to make it go away?
