The Web site on port 80 does not have to be dedicated to WSUS.
In fact, WSUS uses the site on port 80 only to host the self-update tree.
In this way, each client computer does not have to download updates directly from Microsoft on internet therefore, reducing bandwidth and traffic on the network.
You can do this using the Services console or by running the following two commands: net stop wuauservnet start wuauserv Within 6 to 10 minutes, Windows Update will attempt to contact your update server.
Windows Server Update Services server (WSUS) is a central repository on your network which downloads and maintain latest updates from Microsoft update server.
To ensure that the self-update tree is working properly, first make sure a Web site is set up on port 80 of the WSUS server.
Next, type the following at the command prompt of the WSUS server: cscript :\program files\microsoft windows server update services\setup\Install Selfupdate On Port80If you identify a problem and make a configuration change that you hope will resolve it, restart the Windows Update service on the client computer to make the change take effect and begin another update cycle.
The Synchronization Schedule for WSUS server has been kept at hrs.
