18.104.22.168 Software Update Services
Microsoft Software Update Services (SUS) provides the same benefit on local servers as the Windows
Update servers provide on the Internet. It allows you to make your choice of updates available to clients
using Automatic Updates. The SUS server synchronizes with the Windows Update server to obtain the latest
updates, and multiple SUS servers can synchronize with each other.
SUS requires at least a Windows 2000 Server computer with Service Pack 2 configured as a stand-alone
server or member server. It cannot be installed on a domain controller. It also requires Internet Information
Services (IIS). To install SUS, first download the server software from the Microsoft Web site. SUS is
provided as a file, Sussetup.msi, that uses the Windows Installer to install the service. Run this program to
begin the installation. A wizard guides you through the installation process.
When using SUS, you must configure each client to use the SUS server and you must approve updates
before they will be made available to clients. This approval process allows you to pre-test updates before
deploying them across the enterprise. The updates you approve will be installed by clients running
Automatic Updates on their next scheduled connection to the SUS server.
Note: You can remove approval from updates that have been previously
approved. However, this does not remove them from any clients that have
already installed the update.
