[ActiveDir] Root domain naming

[Brad Martin]

I’m in the middle of having an argument with the IT manager about the top-level domain name for our new A.D. deployment.  The manager wants to use a nonstandard name for the domain (ie. Dc1.domain.gd) for the root domain.  My position, which I’ve read a number of places, is that we should use a standard, registered, name for the root.  The manager’s contention is that this domain will never be live on the Net and so we can do whatever we want.  As I said, I’ve always read that you should use a registered name as your root, even if you aren’t going to be live, but there are never reasons given why this is good.  What reasons should I go back to my manager with?   Brad Martin
