YES! it works... but!!! I've download the ZIP file from the site you'r guide states to Copy all the INFs to C:\Windows\Inf\ this task will change the sysoc.inf of the original installation to the one you have in the ZIP file. The file you have there is not compatble to all windows 2003 versions and installations. just don't copy sysoc.inf from the ZIP file use the one from the C:\Windows\Inf\ folder and you will find out that the rest of the guide is 100%.
