  • Hi,

    can you provide more details, otherwise i´m afraid we will missunderstand your case.

    1. Are you talking about a multi-domain AD-Forest or two single-domain forests ?
    2. What do you mean with primary / secondary domain ? 

    Can you please provide fictional names for your domains for a better understand, for example:

    contoso.com, sub.contoso.com or domain.org

    Thanks, pat

  • Thank you for your prompt reply!

    NO, i am not talking about a multi-domain AD-Forest.

    domain controller name:space.net

    Install additional "DC03" Windows Server 2012R2 domain controllers in an existing domain.

    "DC03" want to be Primary Doamin and "DC01" Secondary Domain

    Thanks

  • Hi,

    ah okay i see, i think i understand right now.

    In your case, to make the DC03 to primary, you should move the fsmo roles.

    • To Display the current FSMO-Role Distribution: open cmd, enter: netdom query fsmo

    Then you need to move the FSMO Role, here is a good article which helped me when i did that the first time:

    https://social.technet.microsoft.com/wiki/contents/articles/6736.powershell-move-transfering-or-seizing-fsmo-roles-to-another-domain-controller.aspx?ranMID=24542&ranEAID=TnL5HPStwNw&ranSiteID=TnL5HPStwNw-SZWLHBpg9vJ9bWhcY.PpDw&epi=TnL5HPStwNw-SZWLHBpg9vJ9bWhcY.PpDw&irgwc=1&OCID=AID2000142_aff_7593_1243925&tduid=(ir__d6rbge1ztgkfrlspkk0sohz30n2xjjyia0ahtnc200)(7593)(1243925)(TnL5HPStwNw-SZWLHBpg9vJ9bWhcY.PpDw)()&irclickid=_d6rbge1ztgkfrlspkk0sohz30n2xjjyia0ahtnc200

    Here is an additional microsoft article about the FSMO Placement for Best Practices:

    Hope this helpes

  • Active Directory Domain Controllers are multi-master.  There is no "Primary Domain Controller" and "Secondary Domain Controller" like it was with Windows NT.

    Active Directory has 5 FSMO roles and those roles can be held by a specific Domain Controller

    You can have more information on this here

    https://support.microsoft.com/en-ca/help/197132/active-directory-fsmo-roles-in-windows

    Also, if you want to move the FSMO roles from a DC to another DC, one of those articles may help you
