Can you share more information? What supplicant are you using? 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?

If this is specific to a specific driver and other machines are working fine have you contacted intel/microsoft? Does this have anything to do with ISE besides dot1x not working for a specific client?
