You need to setup Conditional Forwarding on each domain.<br />
<br />
As an example:<br />
<br />
On the Forwarder tab of the DNS server in Domain A, you would add Domain B and Domain C.<br />
<br />
Do this for each domain so the other 2 domains are forwarders.<br />

If you simply ping the NetBIOS domain name of the other domain from your workstation what it the result?<br />
<br />
My guess is that it appends your own DNS suffix.<br />

We have a root domain controller with 3 sub domains. (domain A,B,C)<br />
Each location is separated by a Firewall, But there is a trust between them.<br />
<br />
I was able to permission Joe &nbsp;from Domain A, as a local admin on a server in Domain B.<br />
When he tries to logon through he get an error that the server cant find the domain<br />
<br />

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
