First off, this article is far from being pointless. If you actually read the article and used logic instead of verbally bashing the author, it does give configuration advice, as far as what to do with configuring Lion Server to be the DHCP server and what to look for if you find yourself troubleshooting issues where Lion Server is not working in some fashion.

This is a great article that I am sure many will benefit from. If you are an IT professional, it is just a matter of taking in what the article does contain and just using logic in the process of configuring Lion Server to suite your needs.
