How to troubleshoot DNS issues in an Active Directory domain controller

Professor Robert McMillen shows you the correct way to setup DNS settings in an Active Directory domain controller for Windows Server 2019, 2016, and older. In this tutorial I show you how to fix slowness for people logging in and trying to access shared data by adding in proper DNS settings in your network interface card and DNS manager.

Thank you for this video!! You are probably the only source of proper DNS configuration on Youtube. This settings works perfect and DNS is resolving the way it should.

This SAVED my clients butt! We just retired an old AD/DHCP/DNS server at a client of mine and I shut the old system down last week. After removing it, page load times when going to external websites were suuuper slow and they almost couldn't run payroll on Monday! Sure enough on the new server, the forwarders were set to the old internal Server IP! I updated to Google and bam, back to normal! Thank you for this!

What a great video! I liked the fact that you exposed the most common mistakes, some of those were also my mistakes.

Thank you! For the longest time, I hadn't been able to solve why my PiHole was getting inundated with what seems to be looping DNS calls from Windows DNS Server. Finally, your explanation that I have to setup outside DNS servers under the DNS main DC --> Forwarder was the key that solved the problem! Thank you. Thank You.

I also loved your video on setting up AD on TrueNAS. Very helpful in integrating.
