Heck, I would even settle for a error code -> geekspeak dictionary. Like the event ID database site I mentioned in my first post. As long as it covered just about every event ID there is, and isn't just best guesses by other sysadmins. I assume some of this information is already in the KB. The problem is how to find the appropriate and relevant articles every time.
All I can say, Lars, is that all of this stuff will get much better in Longhorn. I know that's hand waving, but it is true and I have talked to the reliability people several times, including forwarding them some of your related posts.
Longhorn will be better at this. We promise.
