A Microsoft Systems Management Server (SMS) deployment package is available that includes security update MS05-052. Security update MS05-052 applies to Microsoft Internet Explorer 6 Service Pack 1 (SP1) when Internet Explorer 6 with SP1 is used with Microsoft Windows 2000 or with Microsoft Windows XP.
The SMS deployment package also includes a script that enables the SMS 2.0 Software Update Services (SUS) Feature Pack and the SMS 2003 Software Update feature to deploy the appropriate security update to Windows 2000-based computers and to Windows XP-based computers. This script does not install the security update on Microsoft Windows NT 4.0-based computers. Security update MS05-052 is not compatible with Windows NT 4.0.
You can download the SMS deployment package from the Microsoft Download Center. If you authorize security update MS05-052 for languages other than English, French, German, or Japanese, you must download a language-specific version of the SMS deployment package. To use the SMS deployment package, use the /q:a /r:n command-line options in the Distribute Software Updates Wizard.
