Child Domain Removal Windows 2003

Posted on 2011-10-13

So here is the problem that i am having. I work for a client that are a child domain in a larger companies domain. My client is the child domain. Basically the main domain is "" and our domain is "" so our domain is "". i want to clarify that we have our own DC and Exchange servers in house. Honestly i don't know why this was done this way since we don't share any information with the other company.

Is there a way to remove our domain completely and keep it as ""? If so what is the best way on doing that? Or do you think it is easier if we just delete the existing domain (by demoting and removing the DCs) and creating a new one?

I really appreciate any input.

Thank you

    You can create a new domain with the new name and migrate the objects to it.  ADMT is Microsoft's free tool.  There are also third party tools that can help.

    ) will hear the term "prune and graft" referring to this also, more on that here

    ...wish prune and graft was possible

    Depends on how mny resources do you have and how many users/computers/workstations. If not so much and you want to do that in short time, demote child DC and create new one in the new forest. If you wish you may follow an article on my blog at

    In case that you have a lot of resources and you don't want to loose them. Then you need to create new forest with new domain, set up forest trust between 2 forests and migrate users/computers/group/servers etc. from the old child domain to the new one, using free ADMT (Active Directory Migration Tool). ADMT can be downloaded from

    v3.1 for 2003

    v3.2 for 2008

    and really good guide

    All of the above is seconded. The point is that the forest root domain contains critical objects in its directory that your child domain needs to work reliably. So you either need to keep a copy of the forest root, or migrate to a new forest.
    So here is the problem that i am having.
    Technically, you didn't really mention the problem :)
