MSCA 70-291 Windows Server 2003 Exam Prep

Answer - A - A RADUIS server uses UDP port 1812 for authentication and UDP port 1813 for accounting by default.

Kay Takeaway: Remote Authentication Dial In User Service, or RADIUS, is a networking protocol that provides centralized Authentication, Authorization, and Accounting management for computers to connect and use a network service. It runs on the application layer and uses UDP.

To configure a computer running Routing And Remote Access as a RADIUS client, open the server Properties dialog box in the Routing And Remote Access console and select the Security tab. From the Authentication Provider drop-down list box, select RADIUS Authentication. From the Accounting Provider drop-down list box, select RADIUS Accounting.
