Using Windows Installer
Service
Pack 4 (as well as SP3) contains a Windows Installer package file
(Update.msi) which contains all of the information that Windows
Installer requires to install or remove the service pack and to run
the Setup user interface. This package file describes the
relationships among service pack features, components, and
resources. The package file also contains an installation database,
a summary information stream, and data streams for various parts of
the service pack installation.
You can
use the Software Installation and Maintenance feature in Windows
2000, which uses Windows Installer and the Update.msi file to create
a Windows Installer package that installs the service pack. The
Software Installation and Maintenance feature uses a Group Policy
object (GPO) to deploy the package (on networked computers) within
Active Directory containers, such as sites, domains, and
organizational units that are associated with the GPO.
After
you assign the package, Windows Installer installs the service pack
automatically when the users start their computers. The users do not
choose to install the service pack. Note that only a network
administrator or someone who is logged on to a local computer as an
administrator can remove the assigned software.
You can
determine whether the service pack installation was completed
successfully by doing either of the following:
-
Run
winver.exe and view details about the Windows version and
service pack that are running on your computer.
-
Use
the Event Viewer by clicking Control Panel, clicking
Administrative Tools, and then clicking Event Viewer.
To work
around an issue caused by the installation not being completed
successfully, move the computers out of the scope of the service
pack deployment to another organizational unit, restart the
computers, move them back to the organizational unit that has the
service pack deployed, and then restart the computers a second time.
This redeploys the service pack to the client computers. You can use
Active Directory Users and Computers to move the computers from one
organizational unit to another.
