There is no reason to be "afraid" of a downvote as long as you usually write good, topical questions.
The downvotes where not mine, but something is immediately clear:
You actively try to circumvent a restriction set by Microsoft to not allow an SQL server on a Domain Controller. MS put this restriction into place for good reasons and trying to weasel around this is not professional system administration. Since SF is a site exclusively for professional system administrators, we have a very negative opinion about such practices, and this will easily earn you downvotes.
This is is also made clear by the hard-to-find popup notice that is displayed if you hover your mouse over the downvote button: "This question does not show and research effort, is unclear or not usefull".
