Verification of replica failed. Active directory domain controller for the domain XYZ could not be contacted. Ensure that you supplied the correct DNS domain name

    Question

  • I am getting following error while I was trying to add secondary AD server to my domain:

    "Verification of replica failed. Active directory domain controller for the domain XYZ could not be contacted. Ensure that you supplied the correct DNS domain name"

    What I already tried:

    ipconfig /resgisterdns and ipconfig /flushdns on both old Primary Active Directory DNS server 2008 and brand new 2012 server (Clean install of AD DS, to which I am configuring)

    adprep of forest and domain on server 2008

    resolved all connection issues and 2008 is pinging properly

    Firewalls off on both 2008 and 2012

    tried disabling IPv6

    Started all Computer Browser related services and are set to automatic

    Time settings

    I can nslookup from both servers easily and IP seems to be correct

    DNS server (2008) has only one itself's IP in primary DNS server

    DNS has records in domain name (In DNS manager) and Dynamic Updates, click secure only.

    net stop "net logon" 

    net start "net logon"

    -----

    What was the reason to update to 2012?

    ---> My old secondary 2008 DNS server had BSOD because its Active directory was broken

    ----> I already followed steps given at http://www.petri.co.il/delete_failed_dcs_from_ad.htm to delete that server. which is now deleted
