Network policies use conditions, settings, and constraints to authorize a level of access for clients attempting to connect to a network. For Network Access Protection (NAP), you must configure at least one network policy that will be applied to computers that are compliant with the health requirements and at least one network policy that will be applied to computers that are noncompliant. You can also configure a network policy that will be applied to computers that are non-NAP-capable. You might configure additional network polices to specify unique health requirements for different computers or segments of the network.
