NPS / Radius Server is not logging

English OS:
auditpol /get /subcategory:"Network Policy Server"

German OS:
auditpol /get /subcategory:"Netzwerkrichtlinienserver"

English OS:
auditpol /set /subcategory:"Network Policy Server" /success:enable /failure:enable

German OS:
auditpol /set /subcategory:"Netzwerkrichtlinienserver" /success:enable /failure:enable

after this, the NPS service finally writes the important events:
