Скачать или смотреть Windows NPS Server Stops Logging Events (Fixed)

This video shows how to resolve an issue where the event logs randomly stops on a Windows Network Policy Server (NPS). This can be a problem if you're using NPS as a RADIUS server and the logs are missing.

To get the status of the logging, run the command below from an elevated command prompt:
auditpol.exe /get /subcategory:”Network Policy Server”

This command will enable the logging, but I've found it frequently gets turned off again:
auditpol.exe /set /subcategory:”Network Policy Server” /success:enable /failure:enable

The best fix is to enable the logging using this group policy:
Computer Configuration → Windows Settings → Security Settings → Advanced Audit Policy Configuration → System Audit Policies - Local Group Policy Object → Logon/Logoff
