ActiveDirectory Domain and Trust

[Harry J Nathan]

I am trying to create a trust between two domains
(different forest) separated by firewall, firewall don't
have any rules to block anything, it is fully open expect
NAT.
When I use active directory Domain and Trust and enter the
domain name I get a message "domain can't be reached" I
don't know what to do next, I need to create the trust.
Can someone please help me how resolve this problem.
Thanks

Hi Harry-

One thing to be sure of is if you can reach the other domain's DC's. Ping as
well as reverse lookup. If not, you may need to add some host names to DNS
manually. If the only thing your firewall has blocked is NAT you should be
ok there.
