Domain Trust Not Validating

In the console tree right click the domain that contains the trust that you want to verify and then click properties.

Domain trust not validating. Domain trust created but not validatable. The forest functional level is still at windows 2000. Found that their domain was windows 2000 mixed. First of all open the active directory users and computers snap in aduc.

Both dc are on the same network have no firewalls enabled can ping each other. The trust relationship between this workstation and the primary domain failed. Wow i m not sure i wasn t here in march but my guess would be the vpn tunnel had broken then. Fixing trust relationship by domain rejoin.

Make sure the problematic computer account is present in the domain and it s not disabled. To fix this issue i have demoted my red local domain controller renamed dc01 to red dc01 promoted to domain controller re created my lab ad objects added the conditional dns forwarders and created the trust. I do find it peculiar that this is a requirement for the trust to work. As part of the account maintenance process every thirty days the trusting domain controller changes the password stored in the tdo.

When i started here the vpn tunnel between these two sites was already down failed and i had to recreate the tunnel and now that the tunnel is online i m trying to get this dns issue resolved so that i can migrate the child domain. Domain trust created but not validatable. On the trusts tab under either domains trusted by this domain outgoing trusts or domains that trust this domain incoming trusts click the trust to be verified and then click properties. Both domains in a trust relationship share a password which is stored in the tdo object in active directory.

This issue occurs on client and server operating system from windows xp to windows 10 and from windows server 2003 to windows server 2016.
