I'm having an issues with NAC 4.9.4.3 where it randomly reauthenticates. There are no logs on the switch or within ISE to explain why this occurs. The user appears to remain connected. Has anyone experiences this issue?

Hello Everyone, I'm looking for some help with configuring a posture assessment in ISE that will check to see it a machine has IE 11 installed. The policy will run in audit mode.
