    Question Rebuild or demote?

    I have an associate who has a SBS 2003 server / network running Exchange 2003. He's purchased a new HP server with Windows Server 2012 (Standard). He was intending to use this to completely replace his SBS box. Because of an issue with one application running on his SBS box he needs to keep it running for around a year before it can be decommissioned.

    The 2012 server has already been completely setup with Exchange Server 2013 and as an Active Directory / DNS server for his external domain (company.com). His SBS box is currently setup for all of this, too, but with his internal domain (company.local). I've come to the conclusion that we're going to setup split DNS so he can use both boxes now and take advantage of the new hardware, new OS, and new version of Exchange.

    What I'm wondering is if it's best practice to just demote/remove Active Directory / DNS from the new box, leaving Exchange 2013 on there, then joining it to his existing 2003 domain...

    - or -

    should we blow away the new box and start over from scratch? I'm mostly concerned about the Exchange 2013 installation and if demoting/removing all of the Active Directory and DNS stuff and then joining it to a completely different domain will completely throw it off and break it.

    Thoughts?

    Me again ;-))

    Exchange requires a domain member server as its host and modification to AD to run. It will not run on a 2003 AD domain without running the complete installation process - I don't know if you can even run Exchange 2013 in a 2003 AD domain. Re-installing on a new 2012 server and AD will always be the best option.

    cheers, Paul

    Hi Paul. Thanks for the reply. I was just thinking the same thing about whether or not Exchange 2013 will run in a domain at the 2003 functional level. I think I have some digging to do... 8)

    Why not create a trust between the two domains and add secondary/stub DNS zones? You could then give users access to the resources of both.
    We never really grow up, we only learn how to act in public.

    SBS won't do domain trusts. I too suggested this route, but Microsoft in their infinite wisdom removed that rather useful option.

    cheers, Paul
