Hello,
Group Update Provider
Use the Group Update Provider
Specifies one or more computers to act as a LiveUpdate server for the group. For example, you might want to create a Group Update Provider to conserve bandwidth to clients in a remote location over a slow link. In this scenario, the Group Update Provider downloads the latest updates from the server. The Group Update Provider then updates the clients in the group. If the Group Update Provider is offline, the clients contact the server for the updates.
The Group Update Provider can reside in any group.
Note: The Group Update Provider is available only for Windows clients.
