Managing Windows XP Installation Media and Image Versions

When it comes to updating installation media, administrators sometimes choose not to update the CD or the I386 directory on the servers. This can become an issue when a restore is necessary because a lack of core installation files can prevent the successful installation of new server components or add-ins to the server. If your organization has the Windows media copied to an I386 subdirectory on the server and you perform a service pack update, make sure to slipstream the service pack's latest file updates to the I386 subdirectory on the system so that the server-stored files are the same as the versions of the files loaded on the system. Service packs can be run with an -S switch, which slipstreams the necessary updated files to the server. Hotfixes cannot be updated on the installation media, so you can wait until the machine is installed and send the hotfixes down the wire.

Updating Desktop Images

Whether you create images using RIS or third-party imaging products, when post-installation procedures begin to be excessive or time-consuming, it may be time to update existing stored images. When Microsoft provides operating system service packs, it incorporates most of the fixes within the new service packs. During service pack installation, these previous fixes may be uninstalled automatically or the files may simply be overwritten. When this happens, it is possible to have both the service pack and all the original post service pack releases in the Add/Remove Programs listing. In the end, you can simplify troubleshooting operating system issues if only the original operating system installation and the well-tested service pack are installed.

The same principle should be followed when desktop applications have major release updates. A new image should be created with the latest patched applications to deliver the most reliable desktops.

To know when to update desktop images, follow these few simple rules:

• Update images when the operating system has a new major release such as a service pack or if a new version is available.

• Update images when desktop application software vendors release a major upgrade or software revision.

• Update images when post-deployment tasks that can be automated extend the time necessary to complete desktop deployment.

• Update images when hardware platforms change enough to require manual driver installations.

Following these few simple rules will help you manage desktop images to reduce administrative overhead.
