Network Access Protection compatibility (NAP). This feature enables Windows XP computers to leverage the NAP feature in Windows Server 2008.
This is also found in Windows Vista. From a compliance perspective this is a big win, as this element enables users to better protect their network by evaluating the connected system’s heath status,
for example, the antivirus pattern level and the patch level of the respective machine. If the computer at time of connection complies with the prerequisite policy element then the machine is allowed network access,
if the policy is not met then the machine is quarantined to a network segment, which has limited access to resources.
This limited access allows for the machine to be updated to an acceptable level before being scanned again and approved to be used on the production network.

This is a back-ported feature found in Windows Vista.
