Under ideal conditions for a dedicated SUS server, assuming a 100 Mbps server network card capacity with 20% of this capacity consumed as overhead, it will take approximately 30 seconds for a SUS client to download the Windows XP SP2 update from the server.

The following section provides guidance to prevent this situation from occurring.

The following guidance is provided for the minimum SUS server configuration – Intel P700 system with 512MB RAM and a 100 Mbps network card and network connection, which is dedicated to running the SUS server (no domain controller, etc.) and is on a network where the available bandwidth exceeds the bandwidth capacity of the server’s network card.

If your SUS server machines is running additional services or the available network capacity is less than the server network card capacity, you will need to adjust this guidance to reflect your situation.

Introduction Key benefits of using SUS to deploy Windows XP SP2 Situation overview Factors to consider when using SUS to deploy Windows XP SP2 Overall recommendations Summary Windows XP Service Pack 2 (SP2) contains major security improvements designed to provide better protection against hackers, viruses, and worms.

Windows XP SP2 also improves the manageability of the security features in Windows XP and provides more and better information to help users make decisions that may potentially affect their security and privacy.

Microsoft strongly urges customers with Windows XP and Windows XP Service Pack 1-based systems to update to Windows XP SP2 as soon as possible.As a best-practice approach to implementing a managed rollout of Windows XP SP2, customers are encouraged to use a corporate update management solution such as Systems Management Server (SMS) 2003 or Software Update Services (SUS).The following section details considerations for deploying Windows XP SP2 using SUS.Note: SUS is available as a free download to customers with a Windows Server 2003 or Windows 2000 Server license and can be downloaded from Family Id=A7AA96E4-6E41-4F54-972C-AE66A4E4BF6C&displaylang=en Because Windows XP SP2 is a relatively large update (approximately 270 MB), SUS administrators need to consider the impact on internal network traffic and on the machine on which the SUS server is running.For the vast majority of SUS implementations, server and network load will not be a concern and SUS administrators will not have to take mitigation actions described below, although it is recommended that the SUS administrator monitor the performance and load on the SUS server when the update is initially approved.
