Exchange 2003 and 2007 Interoperability - Active Directory Connector uninstall??? RRS feed

  • Question

  • Active Directory Connectors...Ok, call me stupid but I am confused. Exchange 2007 tells me that I need to remove any AD connectors in order to add the new Exchane 2007 server to my existing 2003 org. Ok, well, I read up on the ADC and see that its used with Exchange 5.5 migration to 2003...BUT I see other information that looks like I might need it for other things outside of 5.5 migration...so maybe I should not be uninstalling it?? Can anyone clarify what happens if I get rid of the ADC? I have no existing 5.5 server in my org. All are currently 2003.

    Thanks!!!!!!

  •  Active Directory Connector (ADC) is the component that synchronizes the Microsoft® Windows® 2000 version of the Active Directory® directory service with the Microsoft Exchange Server version 5.5 directory.ADC is a necessary component for achieving coexistence between Exchange Server 5.5 and Exchange 2000 Server

    ------------Refer to <Understanding and Deploying Exchange 2000 Active Directory Connector>

    So, in short, I think that only functionality of ADC is connectivity with exchange 5.5

  • ADC replicates objects from Exchange Server version 5.5 to the Active Directory® directory service in a mixed mode Microsoft Exchange environment and is not supported by Exchange 2007. Exchange 2007 setup requires that all ADC components be removed

    --------Refer to <One or more Active Directory Connector servers were found>

    Install Exchange 2007 on Server 2008 (Relevant case)

  • Yes, I realize that it needs to be removed but is the only functionality of the ADC as connectivity with Exchange 5.5 or do I need to look and see if its in use for Exchange 2003?

  • Does anyone know if this removal process causes downtime?  I have a client that is really scared to run this for fear of downtime but we need to in order to move on with Exchange 2010.

  • Has anyone provided an update?  I am installing 2010 also and do not want to lose my capability to administrate my 2003 Exchange until 2010 has been fully migrated.  I am afraid if I uninstall the AD connector, I will have no way to administrate it.
