I assume the native supplicant on Win hosts. Are you doing computer auth only via eap-tls? Are you enforcing any re-auth timers? How is your adapter power management settings configured? How is your supplicant configured?

Does this have anything to do with ISE besides dot1x not working for a specific client?
