Starting today all iPhones on our corporate network are unable to connect to any of the 4 WiFi access points. I had no issues as of yesterday.
Android devices and laptops have no issues. IOS versions tested are 8.2 and 8.4.
I have rebooted the authentication/NPS server. "Forgot the network" on the phone and also went to General, Reset, Reset Network Settings.
Forgetting the network, then reconnecting does not prompt to accept the certificate any longer also.
I have changed the "Dial-in" settings on the user's Active Directory account to Allow Access and the error is still generated below. I have since switched them back to "Control access through NPS Network Policy" and the settings on the Network Policies has a checkmark for "Ignore user account dial-in properties"
This is the error the server.
