Q: Is there something similar to Network Access Quarantine Control (NAQC) for LANs?
A: Windows Server 2008 (formerly Longhorn) includes a new technology called Network Access Protection (NAP) that provides a comprehensive infrastructure for controlling access to your LAN. NAP integrates with IPsec, 802.1x, DHCP, and VPN remote access and enables you to enforce system health policies on computers before you let them access your network. NAP also lets you update computers as you add or update system health policies, and you can limit noncompliant computers to a restricted network where resources such as antivirus installation files are available to bring the computer into compliance. NAP’s system health policy enforcement is much more sophisticated than the rudimentary scripts you can implement through NAQC. For more NAP-related information and resources, see "Network Access Protection" at http://www.microsoft.com/technet/network/nap/default.mspx.
