Note: When the Apply local firewall rules setting is configured to No, Microsoft recommends also configuring the Display a notification setting to No. Otherwise, users will continue to receive messages that ask if they want to unblock a restricted inbound connection, but the user's response will be ignored. Countermeasure: Configure this setting as appropriate to allow or prevent the display of these notifications. Potential Impact: If you configure this policy setting to Yes, Windows Firewall will display these notifications.
