Change domain name in 2008 R2

Hello,
We have two 2008r2 servers one domain controller and one Exchange and we have about 15 users. This domain was just created. The domain was named  by mistake  (ie domain.com) . If we would have named it domain.local it would have no problem. Right now someone owns that name since it's a .com and can not buy third party public certificates for internal use.  Is there an easy way to fix this. I heard of some rename options, but I just don't want to suffer with issues as a result of a name change for the rest of our life. Has anyone actually done this ??

I am thinking reinstall. Your active directory and such will be so loaded with the old domain I am afraid you will suffer nags forever. Bite the bullet and get on with it. Back up the data you cannot lose but don't lose your mind over this one. Mistakes are made.

Good luck,
Ken

It's never a good idea to rename a domain name.  As a matter of fact even just changing a server name can be a major task if the server is a Domain Controller.  dariusq has listed good links. Clean install may be a lot of work, but it may be wiser in the long run.  If you rename it and you miss a small step, you may see weird errors in the future.  Good Luck.
