Audit Network Policy Server

Applies To: Windows 7, Windows Server 2008 R2

This security policy setting determines whether the operating system generates audit events for RADIUS (IAS) and Network Access Protection (NAP) activity on user access requests (Grant, Deny, Discard, Quarantine, Lock, and Unlock).

NAP events can be used to understand the overall health of the network.

Event volume: Medium to high on servers running Network Policy Server (NPS); moderate on other servers or on client computers

Default: Success and failure

If this policy setting is configured, the following events are generated. The events appear on computers running Windows Server 2008 R2, Windows Server 2008, Windows 7, Windows Vista with Service Pack 2 (SP2), or Windows Vista with Service Pack 1 (SP1).
