Changing the internal domain to a subdomain -- Help!

    Question

  • Hello, so I have a huge project coming up and i was wondering if someone had some experience on this that could give me some advice.

    So,  started working on this company that has an internal domain called.. lets say abc.com  and external alphabetaghama.org   ..  the problem we have is that we cannot get certs for our internal domain for public access like our exchange server fqdn for example is exchange.abc.com ... Someone else owns abc.com which prompted my new boss to fix this and now i have a project to change our internal domain to match our external but I know that the best practice is to have a subdomain as the internal domain and I think that's the route my boss wants to go with..  which brings me to my question.

    What will I have to do to get this accomplished... our external domain name is really just a forward zone and i dont have a forest so does that mean that i will have to build a alphabetaghama.org forest and add a subdomain like corp.alphabetaghama.org  for our internal and then migrate everything over? 

    We currently have exchange 2007 with 2008R2 DC's..  our new domain would be on 2012R2 DCs with the same exchange server..

    Sorry if something doesn't make sense, I'm a little new to a major project like this...

  • Hi,

    Could you please tell more details for what purpose to rebuild the domain structrue?

    If for the reason that the internal domain cannot get public access with exchange, I think we should consider to ask in exchange forum, experts there may have good views regarding the issue here.

    Regarding the internal domain name and external name, Mr. Ace have a good blog on that, check here:

    Hope this helps

    Best regards

    Michael

  • Well, part of the reasoning on my boss's part is that our internal domain name is owned by another company and he thinks that it would be appropriate to have our internal domain match our external domain.  Trust me, if this was my decision i think we are fine the way we are...  I've already changed the URLs for the appropriate Exchange 2007 components to point to the external domain name.

    Would your advice be to just keep things the way they are?

  • Hi,

    This really depends on the requirements. As the Domain restructure is a huge project, we'd better have some experts with good experenses at hand. And if the problem (to get public access) is solved,  it is recommended to have a good consideration if the rebuilding is needed.

    Regarding the internal domain name, maybe you want to have a look into the below MS article:

    How Domain Rename Works

    http://technet.microsoft.com/en-us/library/cc738208(v=WS.10).aspx

    For your reference:

    ADMT Guide: Migrating and Restructuring Active Directory Domains

    http://technet.microsoft.com/en-us/library/cc974332(v=WS.10).aspx

    One thing to mind is ADMT tool may cannot be installed on a Windows Server 2012 DC, so please make sure in the target domain we have a Windows Server 2008 DC to be the ADMT server.
