Thank you for your replies. What prompted me to raise this question was becuase I could not see how I could post an answer to the following question:- serverfault.com/questions/821184/… After reviewing it again today though, I have embarrassingly found out why that is: "Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site. " As I dont have 10 points I cannot post an answer. As I dont have 50 points I cannot post a comment.
