If you decide that the patch is safe to install, you must deploy the update to your production servers in a reliable and efficient way. You have a number of options for deploying patches throughout the enterprise. These include:
Using Software Updates Services (SUS)
Using Systems Management Server (SMS)
SUS provides a way to automatically deploy crucial updates and security rollups to computers throughout a network, without requiring you to visit each computer or write script. For more information about using SUS, see "Software Update Services, Part 1" at http://www.microsoft.com/technet/security/tools/tools/sadsus1.asp .
SMS is an enterprise management tool for delivering configuration and change management of Microsoft Windows server and workstation operating systems. For more information about using SMS to deploy updates, see TechNet article, "Patch Management Using Microsoft Systems Management Server" at http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsolutions/MSM/swdist/pmsmsog.asp .
