  • Domain Services Removal

    hello all

    just after some instruction (safe) for the following.

    Currently have:
    1 virtual Primary Domain Controller (inc dns dhcp)
    1 Physical Secondary domain controller inc DNS

    Im wanting to upgrade the secondary domain controller to 2012 from 2008r2
    the Virtual server is 2011sbs.

    Im wanting to remove the AD role and DNS role from the secondary physical machine before doing so. (i may add the roles back on later. The machine will mainly for WSUS, WDS, Fileshare.

    Just instructions on removing the services would be great.

    many thanks

    Run DCPROMO on the second server to demote it and to remove the roles.

      just tried to do this and getting the following error

      The operation failed because:
      Active Directory Domain Services could not transfer the remaining data in directory partition DC=DomainDnsZones,DC=DOMAINNAME,DC=co,DC=uk to
      Active Directory Domain Controller \\
      "The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles."

        have you transfetrred master roles?
        If you can't - seize them seems to be the best option here.

            Virtual server is an SBS, so FSMOs should be on it already (or major disasters if they are not!)

              thats correct. the virtual DC is primary and holds the GC and FSMO roles
