Removing dead exchange 2003 from exchange 2007 organization RRS feed

  • Question

  • Hello,

    I am a newbe on the Technet so please forgive me some mistakes. I would like to get some info about the following case:

    A couple of years ago the previous exchange administrator did a migration from exchange 2003 to 2007. Exchange 2007 was installed on a new hardware and the Ex 2003 has been left online for some time. Then the machine with Ex2003 was shut down to check if the migration is complete and all works fine only on Ex2007. And the Ex2003 machine has been down since then. In the meantime the prevoius admin left the company and I was hired. So lately I decided to retrieve the hardware where the exchange 2003 was installed. I tried to turn it on and it appears that the OS/hardware is corrupted or demaged so the server is dead with no obvious reason. That leads me to the point - should I try, no matter for costs, to fix the old machine/OS to finally remove the exchange 2003 from the organization? Or maybe is it a safe way to remove all traces of the exchange 2003 from current organization without bringing the old server to life? This way would be better for me, and it could potentially be the only way. The Ex2007 has worked for 1-2 years without problems with 2003 down, but the old server is still visible in the organization (there is a computer object in AD, routing connectors etc), . Could you please guide me what should I check to safely remove the dead server? I've googled a lot and there was some guides, mostly based on removing the server entry via ADSI Edit only, but I think there is more to take care to do the job. I believe that all public folders that was not replicated from 2003 to 2007 (if there are some) are not used anymore (no one cried for them), the other remains on the old 2003 can be lost as well. Thanks in advance for any kind of help.

  • Damian,

    You are right in your #3 above - you will use the steps in the Remove the Exchange Server 2003 server from Active Directory section near the end of the article you found for removing Exchange from the directyory using ADSIEdit:  https://support.microsoft.com/en-us/kb/833396  Only remove the references to the Exchange server itself - do not remove any of the parent containers.  And removing the Exchange 2003 server will not adversely affect your Exchange 2007 systems.

  • The server object and routing connectors are no longer needed, and can be removed safely.

  • You can remove the old server from the directory without recovering the server.  See the following article, and start with the section where they explain how to use ADSIEdit to remove the server:  http://www.msexchange.org/articles-tutorials/exchange-server-2003/migration-deployment/Remove-Exchange-server-entire-Exchange-organization.html  Make sure you follow the instructions in the "How to Remove the First Exchange 2003 Server Computer from the Site" section.  Do NOT complete the section titled "How to completely remove Exchange 2003 from Active Directory".  This will remove your entire Exchange organization - including the operational Exchange 2010 information.

  • Hi,

    I understand that you need to remove dead exchange 2003 from exchange 2007 organization.

    I suggest you can refer to these below articles to complete your actions:

    Hope it's helpful to you .

  • Thank you very much for your help. I will try above solutions soon.

    [EDIT]

    A couple additional questions:

    1. I saw the following article earlier: http://www.msexchange.org/articles-tutorials/exchange-server-2003/migration-deployment/Remove-Exchange-server-entire-Exchange-organization.html The article descibes process when the exchange 2003 is reachable and from the very beginning. The secion about ADSI Edit says about removing Exchange attibutes but does not specify which attibutes (should I remove object CN=<exch 2003 server name> with child objects located under CN=<domain name> -> CN=<administrative group> -> CN=SERVERS ? Or sth else?).

    2. Next thing. You've written "Make sure you follow the instructions in the "How to Remove the First Exchange 2003 Server Computer from the Site" section." - all instructions are high level steps taken under exchange 2003. I do not have access there, moreover - is this neccessary if exchange 2007 organization works OK with exchange 2003 down?

    3. https://support.microsoft.com/en-us/kb/833396 - here we have the steps for removing the exchange server 2003 from windows os and the organization, leaving windows on the machine. I think I can start here: Remove the Exchange Server 2003 server from Active Directory. Question, like on the 1. point: should I remove object CN=<exch 2003 server name> with child objects located under CN=<domain name> -> CN=<administrative group> -> CN=SERVERS ? Or sth else? Is this safe for Exchange 2007 organization?

    4. https://technet.microsoft.com/en-us/library/bb288905(v=exchg.80).aspx - here we have a complete procedure again. I'm a little confused  - now we have section: "To remove the last Exchange 2003 or Exchange 2000 server from an Exchange 2007 organization" - so does the making these steps affect my Exchange 2007 Organization? I assume that the acticle from point 1. says about complete removal of exchanges from AD and here we have the procedure to remove only 2003, even if it is the one and only exchange 2003 and the other exchange is fully functional exchange 2007. So to sum up, I should complete these steps on ADSI Edit:
    - delete the Recipient Update Service (Enterprise Configuration)
    - Write DACL inherit (group) right for the Exchange Servers group should be removed from the root of the domain
    - delete CN=<exch 2003 server name> with child objects located under CN=<domain name> -> CN=<administrative group> -> CN=SERVERS (???)
    - delete routing connectors (???)

    Sorry for potentially dumb questions but I would like to ask twice than blow up the working environment. Sorry for my english as well.

  • Thank you so much, looks like all works fine and I cannot see the references to the old Exchange. Is there anything more I should do?

    - Can I remove the computer object (the one which has Exchange srv installed) from AD?

    - How about these routing connectors?

    Best Regards,

    Damian.
