"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Here is a whole article on Domain Name rename.   It is possible but make sure you understand the impact on your network before you attempt.   Also, make sure that you do a SystemState backup so that you can role back the changes.   Just PLAN before doing this.   Here is the Technet article.
