RADIUS accounting

There are three types of logging for Network Policy Server (NPS):

Event logging.

Used primarily for auditing and troubleshooting connection attempts.
Logging user authentication and accounting requests to a local file.

Used primarily for connection analysis and billing purposes. Also useful as a security investigation tool because it provides you with a method of tracking the activity of a malicious user after an attack.
Logging user authentication and accounting requests to a Microsoft® SQL Server™ XML-compliant database.

Used to allow multiple servers running NPS to have one data source. Also provides the advantages of using a relational database.
