Step-by-step guide: Network Access Quarantine Control

Windows Server 2003's Network Access Quarantine Control (NAQC), part of the Resource Kit, prevents remote users from connecting to your network with machines that aren't secure. Contributor Jonathan Hassell provides step-by-step instructions on how NAQC works and how to configure it.

One of the easiest and arguably most prevalent ways for nefarious software or Internet users to creep onto your network is not through holes in your firewall, or brute-force password attacks, or anything else that might occur at your corporate headquarters or campus. It's through your mobile users, when they try to connect to your business network while on the road. You would expect your business desktops to follow policy, but in the past, mobile users have traditionally been forgotten or grudgingly accepted as exceptions to the rule. However, Windows Server 2003 includes a new feature in its Resource Kit, called Network Access Quarantine Control (NAQC), which allows you to prevent remote users from connecting to your network with machines that aren't up-to-date and secure. NAQC provides a different sort of security and addresses a different, but equally important, sector of communications than VPN or IPSec.
