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 ??
