Ah, how I hate them, let me count the ways…
this microsoft support article in essence says M$ is holding hostage a hotfix that will let you see what processes on a windows 2000 computer are opening what network ports. They could have easily just included a link to the hotfix, but this article seems to me to be saying, ‘we are going to make you pay $200 for a support incident to get a copy of this tool’.
