I am trying to clean up some AD issues I inherited, including an internal domain name being the same as our external domain name. Because of some DNS issues I would like to change the internal domain name from abc.xyz.edu to abc.local. In looking over some of the responses to other similar questions, a number of responses recommended starting all over from scratch. If that is the consensus, how do I go about recreating or backing up/restoring 1000 users/550 computer objects/group policy/etc. when creating a new domain controller from scratch? If using rendom is a viable solution, are there any inherent issues when changing the domain name this way? We have a WinSvr2008R2 DC / virtual WinSvr2012 secondary; are not using Exchange; single forest and tree and am at a 2008R2 function level. Thank you for your help.
