Event ID 6279
Category Logon/Logoff
Sub-Category Audit Network Policy Server
Description The network policy server locked the user account due to repeated failed authentication attempts.

Events which are audited under the Audit Network Policy Server sub-category are triggered when a user's access request are related to RADIUS (IAS) and Network Access Protection (NAP) activity. The requests are of the following types: Lock, Unlock, Grant, Deny, Discard, and Quarantine.

Every IAS and NAP user access request generates an audit event if the Network Policy Server auditing is configured, and if the NAS and IAS roles are installed on the server.

Why does event ID 6279 need to be monitored?
