Microsoft Systems Management Server 2.0

From Microsoft:

Systems Management Server Installer now includes the Windows Installer Step-up Utility (ISU). ISU includes a command-line tool that migrates setup packages from the Systems Management Server Installer format to the Microsoft Windows Installer format, resulting in a Windows Installer setup package with an .msi file name extension. The new setup package can be run on computers that support the Windows Installer service. Systems Management Server Installer also supports previous versions of Systems Management Server Installer scripts and packages. This download also includes a command-line feature (Isu.exe) that you can use to convert executables to Windows Installer packages. These .msi packages created by Systems Management Server Installer can be distributed using Windows 2000 Group Policy; they also support Windows Installer advertisements and repair features.
