It looks like Chapters 20 and 41 got jumbled up in the online version of the HOWTO.
The html file in the URL above has the wrong content. It should contain Chapter 20 "Hosting a Microsoft Distributed File System Tree". Instead, it contains Chapter 41 "Managing TDB Files" (per the file name, msdfs.html).
Additionally, the Chapter 41 links on the index page ALSO point to the msdfs.html file, which I think is incorrect.
