I just finished the first DNS chapter in my Elements book, the first of my three-book series on Server 2008. I always love talking about DNS — it’s a fun topic — but this particular chapter was a joy to write because I mostly threw away the old chapter and wrote an all-new one. In the process, I got a chance to include a lot of coverage of command-line support, now that Microsoft’s gotten serious about letting us do more and more with the command line. It dawned on me, however, that people wanting to refer to my command-line coverage in the chapter might not want to have to look through 100 pages of text, and so I collected all of the CLI DNS commands that I used throughout the chapter into a sort of “DNS cheat sheet.”
It’ll be months before the book arrives, though, and so I thought I’d post this on my site in the hopes that it’ll be of use to someone.
