Your network consists of a single Active Directory domain. You have a single server that runs ISA Server 2006.
The server is configured as a firewall and as a Web proxy. The network contains 300 desktop client computers. All client computers are joined to the domain. Users only have user level privileges on their computers. The internal network is configured to accept Web Proxy connections and Firewall client connections.
You need to deploy Firewall Client for ISA Server to all the desktop client computers. You must achieve this goal by using the minimum amount of administrative effort.
