You check DNS first so the domains see each other right away. I set up forwarders on both sides to make names resolve fast. Then you test pings between the domain controllers to confirm connectivity holds up. But sometimes firewalls block the ports and you tweak those rules quick. Or you add the other domain name in the hosts file for a quick fix if needed.
I open the domains and trusts tool next and pick the external trust option for most cases. You select one way or two way depending on what access you want to allow. And you enter the other domain name carefully so no typos mess things up. Then the wizard asks for trust passwords that match on both ends. Perhaps you choose selective authentication to limit who gets in from the other side.
You validate the trust after creation to see if it works without errors. I run the validation from the tool and watch for any DNS or credential issues that pop up. But if it fails you go back and check the passwords again or the firewall rules you set earlier. Or maybe you recreate the trust with different settings if the first try flops. Then you test user logons across the domains to confirm the link holds.
Also you consider forest trusts when multiple domains sit inside bigger structures. I prefer external ones for simpler setups between separate companies. You might need to enable SID filtering to block certain accounts from crossing over. And you monitor event logs on the controllers for trust related errors that show up later. Perhaps you adjust the trust direction after testing real user scenarios with your team.
Now you keep an eye on replication between the domains so changes sync smooth. I use basic commands to force updates when things lag behind. But you avoid overcomplicating with extra features unless the job demands them. Or you document the whole process for future reference in case someone else handles it. Then you verify group policies apply across the trust to ensure security stays tight.
