Problem: Creating a domain trust

Problem: Creating a domain trust

We have 2 seperate domains which are in seperate forests. They are not in the same Domain namespace. They are physically in the same network. Both domains are Windows 2003 domains. I have the administrator privilages in both domains. I would like to create 2 way trust between the 2 domains. When I start the wizard on Domain A and type the DNS name for  Domain B, it says “The name you specified is not a valid Windows domain name. Is the specified name a Kerberos V5 realm?”. When I retype the DNS domain name for the Domain B the wizard says cannot continue: “”the new trust wizard cannot continue because the specified domain cannot be contacted”.
When I attemp to create the trust from Domain B, it went  through and created the trust. And now I can see it on Domain A’s trusted domains list.
I would like to know if the reason not allowing me to do it from Domain A WILL cause some other problems when we need the trust to work. So I would like to find out what might have caused that. I thought this was a DNS issue.
Any comments are appreciated.


Solution: Creating a domain trust

The secondary DNS is only used when the primary address is unavailable.  It won’t query both.
Forwarders are completely appropriate in this configuration.
