We support a clients Windows 2008 network - 60-70 users. We have upgraded all of their current client machines to Window 7 x64. With XP support expiring shortly we would like to be able to block XP client machines from logging into the network. Some of the users are reconnecting old workstations/laptops to the network and we wish to block this activity.
Is there a Windows 2008 group policy that will allow a minimum client OS to be enforced?
Many thanks in advance.
