MCSA/MCSE Self-Paced Training Kit (Exam 70-270): Installing ...

2-45
Software Update Services (SUS) is a server component installed on a Windows 2000 or
Windows 2003 server inside the corporate firewall. SUS allows for the distribution of critical
updates and security updates; it does not allow the distribution of Service Packs or
driver updates, and it does not have a mechanism to deploy software packages outright.
SUS synchronizes with the public Windows Update site at Microsoft on behalf of your
clients. SUS, which is designed to support up to 15,000 clients, serves as a distribution
point of updates to the clients in your organization in two ways:
Automatically You can create an automatic content distribution point on the SUS
server that will synchronize its content with the content from the Windows Update
website. This option offers clients the same updates as the public server, but cuts
down on Internet traffic by providing the updates locally.
Manually You can also create a content distribution point on a server running
Microsoft Internet Information Services (IIS) version 5.0 or later. This option lets
you specify which updates are available.
You can also control which server each Windows client connects to for updates (if you
are running more than one SUS server across multiple sites), as well as schedule when
the client should perform the installations of critical updates.
Installing SUS
You can install the Software Update Services server component on a server running
either Windows 2000 Server or Windows Server 2003. The computer should meet the
following system requirements:
■ Pentium III 700 MHz or better processor
■ 512 MB of RAM
■ 6 GB of available hard disk space formatted with NTFS
■ Windows 2000 Server (with Service Pack 2 or later) or Windows Server 2003
■ IIS 5.0 or later
■ Internet Explorer 6.0 or later
Lesson 6 Activating and Updating Windows XP Professional
The SUS component is available for download from (http://www.microsoft.com/
windows2000/windowsupdate/sus/default.asp). After the download is complete, double-click
the setup file to begin the installation process and simply follow the menu
prompts for a Typical installation (a Custom installation lets you choose the folder
where the service is installed and the location where updates are stored).
To Use Group Policy to Configure Clients to Access SUS
After SUS is installed in your environment, you need to configure the client systems to
use it—otherwise, they will just keep using the Windows Update public server instead.
