Verification of replica failed. Trying to promote Server 2012 Domain Controller


  • I am in the process of promoting a Server 2012 machine to a Domain Controller.  I continue to get the Verification of replica failed error. 

    When I first recieved the error I went to Active Directory Domains and Trusts and found that it said the Current Domain Function Level was set to 2000. So I elevated to Windows Server 2003 and attempted to promote the Server 2012 machine again and I received the same error. I found several articles that explains this needs to be done in Domains and Trust not Users and Computers and that is what I had done here but I have to be missing something, please advise.

  • Hi

     In first picture it gets "domain functional level" but the error related to forest functional level.Just check your forest functional level and if it is not at least 2003 then raise.
