Planning Redundancy for a NAP Health Policy Server
Applies To: Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Vista
To provide redundancy for a NAP health policy server, you must configure your NAP enforcement servers to forward connection requests to a remote RADIUS server group that contains a primary and secondary health policy server. The NAP configuration of your primary health policy server can be exported to file and then imported to the secondary server so that each is configured identically. If the NAP enforcement server cannot contact the primary health policy server, it will use the secondary health policy server for client health validation. See the following figure.
