NAP is available only in server 2008 or above. It is not available in 2003, and it is a little more complicated to deploy but in short, you basically configure a connection policy for computers to connect. If they meet certain conditions that are required, they are allowed inside the network, if not they can be sent to a remediation network where they can try to meet the compliance checks. You also have to enable NAP clients through Group Policy.
