802.1x windows group policy

We have strange issue , some users disconnected and connected again within few seconds.

which result Cisco NAC agent started again to check posture status , but no logs on the switch that the ports were down also IP Phones connected between switch and PC.

we noticed that there is group policy pushed from Domain in the same time.

any one faced this issue (when apply group policy , the network card reset?)

how can I confirm that this is not "session termination initiated from ISE" .

1. Make and model of the phone

3. Make and model of the switch
