The purpose of this article is to serve as a checklist for whenever I encounter an existing SQL Server instance or when I'm to implement a new SQL Server instance. There are a bunch of things that I want to check out, verify etc. Most of these aren't particulary difficult, but the trick is to remember to do them. Hence this article, a cheat-sheet. It is not meant to be exhaustive. There will always be more stuff to put in here, or things that you and I prefer to do differently. And, this will always be a work in-progress state.
