  • If, i understand you correctly parent domain controller means you want to say primary domain controller & additional domain controller is the other domain controller in the same site & you want to get rid off by demoting & repromote it.

    The easiest way is dcpromo /forceremoval which requires additional step of metadata cleanup, since graceful demotion is not working in your scenario.

    I would request prior to demoting the ADC, make sure you transfer/seize(seize is done in disaster recovery scenario & once you seize the FSMO role that dc can be put back even though its working fine & the option to bring it back is remove AD & then delete everything from AD references, followed by metadata cleanup to reconfigure the server as an DC) all the roles like FSMO,dhcp or any other role prior to demotion.

    Steps to perform metadata cleanup.

  • Hello,

    a parent DC is normally mentioned if you work with child domains also. Please elaborate your setup.

    If the DC is in the same domain as the first one please use the support tools and provide the following output files:

    ipconfig /all >c:\ipconfig.txt [all DCs]
    dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt
    repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt  ["dc* is a place holder for the starting name of the DCs if they all begin the same (if more then one DC exists)]
    dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045)

    As the output will become large, DON'T post them into the thread, please use Windows Sky Drive(with open access!) and add the link from it here. Also the /e in dcdiag scans the complete forest, so better run it on COB.
