This error is typically returned when an exception that is not identified by some other error occurs. Open an elevated PowerShell window and run the following command to view the current auditing setting for NPS events.Īuditpol.exe /get /subcategory:”Network Policy Server” The lack of 62 events in the event log indicates that auditing for NPS events is not enabled. Here, the only events recorded are NPS informational events indicating which domain controller the NPS server is using to perform authentication. In some cases, administrators may find none of these events recorded even though user authentication is working correctly. The two most common recorded events are event IDs 6272 (access granted) and 6273 (access denied).
When configured correctly, event logs will record the disposition of all authentication requests, allowed or denied. Administrators can find these pertinent events by opening the Event Viewer on the NPS server ( eventvwr.msc) and navigating to Custom View > Server Roles > Network Policy and Access Services.
