Hi Guys

The parentdomain information in the current subdomain server is wrong, because the correct parent domain has been down. I just changed the host name and IP of a secondary domain controller to the parent domain server information that has been down, and this secondary domain controller has the correct subdomain server. Can this relationship be repaired.

    Probably not. You may be able to do something via the ADMT tool.

    Hi @Tony Mu •,

    If all domain controllers in Parent domain are down , the trust relationship between child and prarent cannot be repaired. To repair the trust issue, you should have at least one domain controller in parent domain available and working fine to establish the trust. Don't forget to launch metadacleanup to remove offline domain controller , if it's not possible to repair it.
