  • Exchange 2k3 with a 2k8 Domain Controllers

    Hi,

    I have a client who has a Windows 2008 Domain Controllers with a Domain Functional Level of Windows Server 2008 and a Forest Functional Level of Windows 2000 Server

    The Question is: Can the client install Exchange 2003 Server given the above information about his Active Directory ?


    Note : The Exchange Server will be installed on a Windows 2003 Enterprise Edition Server, but I'm wondering about the AD Support.

    Does the customer have Exchange already? Are the 2K8 DCs 32-bit or 64-bit?

    The only issue I can see is in preparing the AD Schema for Exchange if it's not already done. I don't know if the Exchange 2003 Setup Wizard can handle 2K8 DCs for forestprep and domainprep. I would think if it can't though you could use the Exchange 2007 adprep tools, as it supports a mixed 2003/2007 Environment.

      No. They only have its license, but not yet installed.

      32-bit DC.

      This is the main point I'm wondering about !

        Doesn't say anything specifically about adprep and forestprep, but this link from the MS Exchange blog does state that Exchange 2003 is supported with 2008 Domain Controllers.

        Also found this in the archives - if Sembee says it'll work then that's usually pretty conclusive.

          You can run prep for domain and the forest from the Exchange 2003 server. It does not have to be run on the domain controllers.
          Therefore as it is a supported scenario, you shouldn't have any problems deploying it. Just run prep from te Exchange server.

            Hi,

            So lets summarize this :
            1. Install Windows 2003 Server
            2. Join this server to the Windows 2008 Domain
            3. Then Insert the CD of Exchange 2003 into the Windows Server 2003 CD drive
            4. Run Domain Prep and Forest Prep from this windows 2003 server.
            So this will prepare the Windows Server 2008 AD, even through they are with a Domain Functional Level of Windows Server 2008 and a Forest Functional Level of Windows 2000 Server.

            Interesting....

              That is correct.
              You will need to install Exchange 2003 and then immediately Exchge 2003 SP2 for it to work correctly.
