Forest Trust

Hi

I have created a Forest Trust with two different domain connected by a VPN. The problem I have is when I go to validate the trusted domains it respond that their is no Active Directory to validate the foreign trusted domain.

Is it easy to fix this?

Thanks

I would start with DNS. A lot of times this will either be that DNS and the domain forwarders are not set up correctly, OR .... the domain is a single barreled domain name (eg domainname instead of domainname.ext).

Can you ping the domain name?

There must be DNS failure is there which causing you are not able to get it validated

Check below post for resolving name resolution problem

Also ensure that active directory ports are opened correctly between both domains
Check below article for more details regarding ports

Also download Portqueryui Tool from Microsoft and find out if any network port issues between both Domain controllers

On one of my DC I have this message when I try to open Active Directory Domain & Trust.

( The configuration informations describing this enterprise is not available. The RPC server is not available. )

Maybe that's why I'm not able to validate. Is their an easy way to correct this?

I have this when I run the DNS tests:
dns.log

Your Forest Trust has never worked correct? If so .. remove it and re-run your tests.

If they pass .. verify your forwarder to the new domain works and can verify the destination DC. If you can do this try to rebuild your Trust again.

If it fails again .. repost
