Hi,

We have a root domain controller with 3 sub domains. (domain A,B,C)
Each location is separated by a Firewall, But there is a trust between them.

I was able to permission Joe  from Domain A, as a local admin on a server in Domain B.
When he tries to logon through he get an error that the server cant find the domain

What can be the problem?

You need to setup Conditional Forwarding on each domain.

As an example:

On the Forwarder tab of the DNS server in Domain A, you would add Domain B and Domain C.

Do this for each domain so the other 2 domains are forwarders.

If you simply ping the NetBIOS domain name of the other domain from your workstation what it the result?

My guess is that it appends your own DNS suffix.

If no response then there's a firewall blocking things.  You may need to configure the firewall for DS, and DNS traffic.
