Hello and thanks for writing the article.
I have also written an article on how to get into a SQL server when completely locked out so I feel your pain when people say "how can you write about this, are you a hacker or terrorist?" Shame on them!
There are many real world scenarios where you have no choice but to find a way into a SQL server. As long as you have perissions from the company you are fine.
Here's another thought. If the SQL server is using Mixed Mode you can use a brute force tool to figure out the SA account.
It's good for DBA's to know how to get into a SQL server so that you have help prevent from others doing the same thing. Also, if you don't have physical access or don't have server access then there isn't much you can do to get in unless you know of a user account that had access to the SQL server.
If we DBA's don't talk about this topic, you can bet the house that the bad guys are.
