The Routing and Remote Access service can log all the records of authentication and accounting information for connection attempts when

Windows authentication or accounting is enabled. This can be done by enabling the log authentication requests in the properties of the

Remote Access Logging folder, in the Routing and Remote Access snap-in , where you can configure the type of activity to log, i.e., accounting

or authentication activity and log file settings.

This information is stored in the form of a log file in '%SystemRoot%System32LogFiles' folder. For each authentication attempt, the name of

the remote access policy , that either accepted or rejected the connection attempt, is recorded. The logged information is useful to track

remote access usage, and authentication attempts.
