Renaming of Domains RRS feed

  • Question

  • Hi There,

    We have recently created a new internal domain structure, which now has to be changed.

    Essentially we have a parent domain named corp.domain.com and a child domain named childdomain.corp.domain.com

    We need to change the domain.com to a new name, with almost immediate effect.

    My first question is, can this be done? we are running windows server 2008 R2 domain controllers. And my second question is , what are the complexities behind it seeing there is a child domain in place.


    Any help would be gratefully received.

  • Hello,

    this requires the renaming from all domains in the forest.

    If you run Exchange 2007 or higher then domain rename is NOT possible without removing Exchange.

    Also renaming is critical and may result in problems you won't have. Think about using ADMT to migrate to a new name.

    Is that basically an optical change ONLY. Then you can think about using other UPN suffixes, which is done without any renaming.

    This should be done only if really, really, really necessary. It can have unforeseen consequences unless you carefully review all of your applications, hosts, devices, security, etc., not just because of the child domain but in general.

    The post rename cleanup job can be big. You should carefully research the extent of the rename process, determine everything that needs to be manually configured afterwards and plan for it meticulously so that the phones don't drive you crazy.

    For example, let's say you have a network share like \\domain\dfs, after the rename, your DFS network share may have to be manually changed. Look for anything that uses the domain name or the NetBIOS name for access or authentication.

  • Hello,

    Here's an article by Justin Gao that details the process of renaming the domain in Server 2008R2.

    Also, more info from TechNet :

  • Hello,

    Just found this article, looks like you may have to also rename the child domain.
