This article describes how to disable the warning message that appears when you try to install Windows 2000 Service Pack 3 (SP3) on a computer on which previous versions of post-SP3 hotfixes have been installed.
When you install SP3 for Windows 2000 on a computer on which a previous version of a post-SP3 hotfix is installed, you may receive the following "blocklist" message:
This Service Pack contains files that are missing some of the fixes which were previously installed on this computer. To prevent possible problems, these files will not be installed by the Service Pack.
In order to have these fixes contained in both the Service Pack and the previously installed Hotfixes, you must obtain and install the updated versions of the following hotfixes prior to or following the installation of the Service Pack. These hotfixes are also listed in the svcpack.log file.
To prevent the "blocklist" warning message from appearing when you install SP3 for Windows 2000, delete the Updtblk.inf file from the I386\Update folder of the installation source before you install the service pack. To do this, extract the installation files to a folder by running the w2ksp3.exe -x command from the installation media.
