For many IT Pros supporting Windows systems, getting hotfixes from MS's Product Support Services (PSS) seems to be a black art. In theory, all you have to do is to call in to Microsoft, tell them the KB and you'll get an email with a URL to the patch and the password for the zipped hotfix file. This should be easy - and judging from my last attempt it works as advertised. However, I've heard a lot of tales from IT Pros (in newsgroups, etc) that suggest they've had a different and less pleasant experience.
Well - MS has done something cool and has put up the Hotfix Request Web Submission Form where you can ask for hot fixes. I'm told this is still in beta and does not yet handle all hot fixes, but it's worth a try.
