    Hi,

    we are using CPPM as a Radius Server that is connected to AD. We use PEAP without certifactes. Clients with Win8/10 have no problems.

    Some cients with Win7 have problem that periodically their PC doesn't respond to 802.1x requset. At Acess tracker we see TIMEOUT with 9002 error. When we try to re-authetincate client using switch's CLI (Dell Power Connect 5500) ther is no response from PC. PC behaves like there is no 802.1x supplicant and switch is pushing PC to Guest VLAN. After situation like that we have to unplug and plug in PC's ehternet cable.

    Did you just recently change the server certificate on the radius server?
