forest domain rename in windows 2012 RRS feed

  • Question

  • I have to expand our current Windows 2012 network, which was setup by previous sysadmin .
    The problem is that my current forest and root domain is child.domain.com it should be domain.com
    The goal is to keep child.domain.com as a child domain but root forest should be domain.com
    So is it possible to rename the root forest domain, but still keep that domain name as a child domain for existing domain users ?
    Basically I want only rename the forest domain name and keep current domain name as child domain name .
    the goal is if I need to create more child domain in existing tree they will be :
    newname.domain.com and not newdomain.child.domain.com
    Hope that makes sense.
    never done domain rename before , thanks in advance

    Or, don't even do it.  Rebuild the domain properly.  Domain rename is not a recommended practice.  Depending on what you have running in your domain, it might simply break things.

  • That would be my recommendation.  Time-consuming, yes.  But, have you tested all the applications that run in your domain to see that they can work after a domain rename?  For example, unless something has changed, if you are running Exchange, you cannot perform a domain rename without breaking Exchange.

  • I think the bigger question is why to you want to change the forest root to domain.com?

    Why is there a need to use that instead of using child.domain.com?

    What is it you are trying to accomplish with that particular name?

    Thanks

    Hi Ed ,

    here is why I want to change the domain name, is there another way do reorganize the AD ?

    I did a lot of researches , we are growing company I want to make sure that our AD is well build.

    so my understanding that the best AD practice is domain.com and then for child domains child.domain.com
