  • Adding second Exchange server to Domain

    My currennt environment consists of
    2 - Server 2003 SP1 DC's - DHCP, DNS, GC
    1 - Exchange 2003 SP1 - Member Server

    I need to add a second Exchange 2003 Server to my domain for fail over purposes.

    Scenario
    Prod Exchange server has some issues. I want to try to fix them, but if it fails, my new exchange server will be there waiting.

    What steps do I take to do to add a new Exchange server to my Domain. I know it will be a different name.

    1. What steps to do I need to perform to get my mail boxes to the new Exchange Server?
    2. Will I have to change my MX record? (I have all mail going through Message Labs before it gets to me. I am assuming they know of an IP address to go to...or can I leave the Old mail server up and it will look for the mail boxes on the new server?)
    3. How do I handle the Client machines? Will they know abou the new server automatically? Do I have to point to this new Exchange server manually?

    spepi,

    The following should help you out:

    1. http://www.msexchange.org/tutorials/...ox_Wizard.html

    2. When you add your second exchange server AD knows about it. Mails entering your oganisation will be routed to the second exchange server.

    3. I believe if you already have outlook configured to point to your first server and the mailboxes are automatically moved then your Outlook will be configured to point automatically to the second exchange server. If I could get onto my home network for you I would get a definitive answer for you.

      If the primary Exchange server has issues and you have another server that can take Exchange, then I would just do a swing migration, get all the data off and rebuild the original.

      Thus...

      1. Install Exchange.
      2. Replicate public and system folders.
      3. Wait
      4. Move Mailboxes using Move Mailbox wizard.
      5. Wait.

      As long as both servers are alive, the Outlook users will be redirected to the new server automatically. No user or admin intervention required. They may not even notice.
      Inbound email will automatically be routed to the correct server. However if you have moved all the mailboxes across, then simply update your firewall to point at the new server.
      The only issue comes with OWA and other remote access. If you are using SSL then you will need to move the certificate across and update the mapping. Any users hitting the old server will be redirected to the new server and if the new server's real name doesn't resolve on the internet, then they will fail to connect.

      To correctly remove the old server so that you can rebuild it or whatever, follow this kb article: http://support.microsoft.com/default.aspx?kbid=822931

      It is important that you remove Exchange correctly, otherwise you get a mess on your hands.

        Re: Adding second Exchange server to Domain

        Hi to all,



        All the informations already described are very interesting but is it possible to have a little bit more ?

        I also would like to migrate my exchange 2000 to a new hardware (in the same w2k domain and without using the procedure defined in KB 297289)


        During the installation process of my new Exchange, the system will recognize itself the first Exchange server ? I suppose that I don't need to run the forestprep and adprep commands ?

        Thansk in advance for your help.

          You need to forest prep and domain prep for Exchange 2003.
          When you put the Exchange CD in to the machine, it will autoplay. Select the option to co-exist with existing Exchange 2000 machines and then follow the checklist.

          There is nothing automatic from that point onwards. You have to set the replication of the public and system folders yourself, you have to make the other changes outlined in the KB articles that I pointed to and you have to move the mailboxes using the move mailbox wizard.

            First of all, sorry for this late answer Simon.


            I think I didnít explain correctly my situation. I have 2x w2k DC (mail and file server) and would like to install a third w2k DC with Exchange 2000 (in the same domain) on a new hardware.

            If I install Exchange 2000 on the third DC, the setup will recognize the first Exchange 2000 ?

            Thank you

              You do know that it is best practise to install Exchange on to a member server - not a domain controller? If you already have two domain controllers then I would install Exchange on to a member server instead. It will be a lot happier.

              However, as long as the server is a member of the same domain as the original Exchange server then it will pick up the Exchange org automatically.
              No data will be replicated to the new server without administrator intervention. You have to setup replication of public and system folders yourself.

                Re: Adding second Exchange server to Domain

                Hi Simon,


                You're right: it's better to install exchange on a member server but the fact is that I would like to remove the original Exchange, after migrating exchange himself, fsmo roles, global catalog ... The new one will replace the old one and if I absolutely want to install the new exchange on a DC that's because I want to keep two DC's in my domain.

                From this side, it's OK but can I install the second exchange 2000 before to promote ?

                About all the replication steps, I will see when I will begin ...

                Thanks again

                  You should not change the role of the server once Exchange is installed.
                  Therefore if you are going to make this machine a domain controller then you should do that before installing Exchange.

                  DCPROMO on Exchange, either in or out as a domain controller, will break Exchange - usually OWA and anything else using IIS.

                  However if you have a third machine, I would be looking to put Exchange on to a member server, get everything off the current machine that has "issues", then DCPROMO it out, wipe and rebuild as a straight domain controller.
