Your network consists of one Active Directory domain and one IP subnet. All servers run Windows Server 2008. All client computers run Windows Vista.
The servers are configured as shown in the following table:
All network switches used for client connections are unmanaged. Some users connect to the local area network (LAN) from client computers that are joined to a workgroup. Some client computers do not have the latest Microsoft updates installed.
You need to recommend a Network Access Protection (NAP) solution to protect the network.
The solution must meet the following requirements:
- Only computers that are joined to the domain must be able to connect to servers in the domain.
- Only computers that have the latest Microsoft updates installed must be able to connect to servers in the domain.
