To participate in a NAP deployment, computers and devices that are not running one of these operating systems must be exempt from NAP health evaluation. Other devices might be compatible if they are supported by a NAP partner. For more information, see Network Access Protection Partners (http://go.microsoft.com/fwlink/?LinkID=127724).
