Network Access Protection (NAP) is a policy enforcement platform built into Windows 7, Windows Vista, and Windows Server 2008 operating system that lets you better protect network assets by enforcing compliance with system health requirements.

Configuration Manager 2007 Network Access Protection lets you include software updates in your system health requirements. Configuration Manager NAP policies define which software updates to include, and a Configuration Manager System Health Validator point passes the client's compliant or non-compliant health state to the Network Policy Server. The Network Policy Server then determines whether the client has full or restricted network access, and whether non-compliant clients will be brought into compliance through remediation.

Remediation with Configuration Manager 2007 Network Access Protection requires that the software updates feature in Configuration Manager is configured and operational so that a non-compliant computer can be automatically brought into compliance. For information about configuring software updates, see Software Updates in Configuration Manager.
