You configure computers to use this option by setting them to use the WSUS server and then configuring the WSUS server so that it does not store updates locally. wsus server used as source of update files and approvals The typical WSUS deployment has both updates and approvals coming from the same location. You configure clients to use the WSUS server through Group Policy. You learn how to configure the appropriate policy in Lesson 2 of this chapter. WSUS Topologies You can choose from several ways to deploy WSUS. The way that you choose often depends on issues of bandwidth utilization and administrative responsibility. In a single WSUS deployment you deploy a WSUS server on the organizational network that synchronizes with the Microsoft Update servers on the Internet. Clients on the organizational network retrieve updates directly from this server. The WSUS server administrator approves updates for distribution. This is the most common type of WSUS deployment and a single WSUS SP2 server can function as the update server for up to 25 000 computers running the Windows 7 operating system. In general this type of deployment does not work well for organizations that have a large number of branch offices because branch office client computers each have to retrieve updates from the central WSUS server over a WAN link. Although you can configure clients in branch offices to retrieve only approval data from the head office WSUS server a single WSUS server can function either as an approvals-only server or as an approvals and updates server. A single WSUS server cannot function as an approvals-only server for one group of clients and an approvals and updates server for another group of clients. This is why many organizations deploy multiple WSUS servers allowing bandwidth efficiencies to be realized in each branch office. The options for the deployment of multiple WSUS servers are .
