Sever domain change

Posted on 2011-05-12

I have another remote office which currently has a 2008 server on its own domain; I would like to join that server to our domain in the main office, all the VPN links are up and running.
Is it just a case of removing the active directory off the remote server and changing it to a workgroup then joining the main office domain or will there be more to it?

    Presumably it is a domain controller?

    If so, just beware that you will lose all domain info and exchange servers (if there are any in that domain will stop working also). Any PCs joined to that domain will need to be reconfigured for the new domain and any users will need their own user accounts in the new domain.

    Type DCPromo from command line and click ok. Advise that it is the last domain controller in the domain (If it is) and reboot. When it comes back up, use the administrator account it just asked you to set a pssword for to log on and add it to the new domain.

    You can create a trust between two domain, in this way users of a domain can be authenticated in another domain.

    Another case is that you want everything under one domain, then it must necessarily remove a domain and put everything under one domain. This leads to the loss of users, permissions on folders, profiles on computers etc etc..

    Making trust, everything remains as is, and users can use the "Domain A" for them to access folders "Domain B ".

    What operating system are your domain controllers?
    The two domains are completely separate (eg and

    If you decide fo the Trust , you can view here

    you will just need to build up Trust between both the domains nothing else is required, once trust is build then user from either domain can access the resources for any domain

    follow to do so
