Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest 
critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop 
systems that are running Windows 2000 Professional or Windows XP Professional.

For more information about how to deploy this security update with Software Update Services, visit the 
Software Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing 
updates. By using SMS, administrators can identify Windows-based systems that require security updates and 
to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end 
users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the 
SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack 
to help deploy security updates. For information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to 
provide broad support for security bulletin update detection and deployment. Some software updates may not 
be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to 
target updates to specific systems. For more information about this procedure, see the following Web site. 
Some security updates require administrative rights following a restart of the system. Administrators can 
use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the 
SMS 2.0 Administration Feature Pack) to install these updates.
