There are several solutions that address this problem at the networking level. Quarantine solutions from major network players (Cisco, Nortel, etc) can let you define a policy that would allow or prevent devices from accessing network resources. Additional advantages include the ability to inspect anti-virus and patch levels on the machines before granting network access as well as defining 'restricted' networks for devices that only meet partial criteria (valid guest devices only get Internet access type of thing).
The downside is that these can be somewhat expensive. If you have the time to wait for the software to release, I would check out Microsoft Network Access Protection (NAP) which for a Windows DHCP environment provides a free built in component to the OS that provides similar functionality. However, it is currently in Beta.
