Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server 2008, Windows Server Update Services

There is a discussion of the advantages and limitations of setting up WSUS server hierarchies in "WSUS Server Hierarchies" in Choose a Type of WSUS Deployment earlier in this guide.

To connect a downstream server to an upstream server

  1. In the left pane of the WSUS Administration console, click Options.

  2. Select the Update Source and Proxy Server option and click the Update Source tab.

  3. Select the Synchronize from another Windows Server Update Services server check box, and then type the server name and port number in the corresponding boxes.

  4. If you are planning to use SSL for this connection, select the Use SSL when synchronizing update information check box. The port used for this connection will be 443.

  5. If you want this server to be a replica of the upstream server, select the This server is a replica of the upstream server check box.

  6. Click OK.


When you configure a downstream server, you should make sure that the update languages it supports are a subset of the languages supported on its upstream server. If you choose a language on a downstream server that is not supported on an upstream server, you will not be able to get updates in that language. To remind you of this issue, a task will appear on the home page of the downstream server.


Maximum number of downstream servers talking to upstream root server should not exceed.1000
