„In a simple scenario, each client computer on your account has a direct connection to the Internet and checks for new updates.

„Rumor technology enables all computers in a workgroup to share downloaded files, which controls Internet traffic and minimizes expensive downloads.

„Internet Independent Updating (IIU) enables any computer on the network to get information from the update site, even if that computer does not have an Internet connection, as long as at least one computer on the network is configured as a relay server.

Retrieving updates

Five minutes after a client computer starts, and at regular intervals throughout the day, the Enforced Client client software checks if updates are available. If they are, the client computer pulls them from another computer on the network (via Rumor technology) or downloads them directly from the Internet site.
