Oh, yes, that is all quite straight forward. I am still curious how y'all figured out what is a hotfix type 1 -vs- hotfix type 2? I've been fighting with this for years. My assessment was that no two service packs, or hot fixes were alike, as far as installing. Which, I found typical of Microsoft. Over the years, I have written a cludge of cheesy install scripts to remotely add files and force updates to the registry, even HKEY_CLASSES_ROOT. Modifying the script looks trivial. It's just the authoritative, or master list of ALL critical updates and how they're applied that's a mystery to me. I would prefer to write a perl script that parses the header of each file to determine what type of install, and which OS it belongs, and from that determine which update goes into which XPCREATE directory (SPACKS, SVC-XXX). So, I guess I would prefer to write a script that copies the files from the SUS downloads and places them in the correct XPCREATE directory by reading what is there, as oppossed to modify someone elses script that hardcoded what the updates are. That would make the script much more dynamic, in that it would figure out what goes where based on what is actually in the SUS download directory. Thanks, -arf
