Network Access Protection (NAP) in Configuration Manager 2007 is complementary to and not a replacement of the software updates feature inConfiguration Manager 2007. You must have software updates configured with software update packages before you can create Configuration Manager NAP policies.

No - computers periodically scan to see whether they require software updates in deployments targeted to them. When they have been configured with a deadline, they will be installed automatically.

Yes - although this is not under the control of Configuration Manager. Instead, it is under the control of the configuration of policies on the Windows Network Policy Server.

Computers can be granted restricted network access until the required software updates are installed.


Yes - although this is not under the control of Configuration Manager. Instead, it is under the control of the configuration of policies on the Windows Network Policy Server.

Software updates can be targeted to specific computers for phased deployment.

Yes, using collections.

No - NAP policies are automatically targeted to all computers assigned to the site, and Configuration Manager NAP policies flow down the Configuration Manager hierarchy. Collections are not used for targeting.

Supported by all Configuration Manager clients.


No - only NAP-capable clients such as Windows Vista, Windows Server 2008, and Windows XP Service Pack 3.

Client agent is enabled by default.
