Around a week ago I redid my lab network and added 2 new domain controllers. I used one of my website domains as the lab domain to mimic how a corporation could be setup.<\/p>\n\n\n\n

So the domain for my network was \u201cvoltdrift\u201d<\/strong> and the website domain is externally hosted with the domain of \u201cwww.voltdrift.com<\/a><\/strong>\u201c<\/p>\n\n\n\n

The Problem: DNS will not resolve subdomains.<\/h3>\n\n\n\n

Ones I was done I noticed I could not get to the website. The DNS on the domain controller would not resolve it. I thought I knew how to fix this and all I needed was a new delegation for the \u201cwww\u201d subdomain. I could have sworn that\u2019s how I did it on Windows Server 2012 but for some reason, it would not work in Windows Server 2019.<\/p>\n\n\n\n

DNS Conditional Forward<\/h3>\n\n\n\n

So after a few hours of messing with it off and doing some reading, it seemed like a \u201cConditional Forward\u201d was what I needed. But there was a problem. When I tried to add one I got this error.<\/p>\n\n\n\n

\u201cA problem occurred while trying to add the conditional forwarder. A zone configuration problem occurred.\u201d<\/p>\n\n\n\n

\"<\/figure>\n\n\n\n

It seems that because my local domain is \u201cvoltdrift\u201d the domain controller \/ DNS did not want to add any conditional forward rules dealing with that domain.<\/p>\n\n\n\n

The Work Around<\/h3>\n\n\n\n

The way to get around this error is to trick the DNS server into thinking it is not in control of that domain\/subdomain. Or at least that\u2019s how I understand it. We do this by adding a new delegation to the DNS server for that subdomain.<\/p>\n\n\n\n

\"delegated<\/figure>\n\n\n\n

Then we point that delegation to our Domain Controller \/ DNS server. I know it seems kind of silly. I have 2 so in my case, I pointed it to both of them.<\/p>\n\n\n\n

\"name<\/figure>\n\n\n\n
\"name<\/figure>\n\n\n\n

Now we can setup a new conditional forward without the error.<\/p>\n\n\n\n

\"new<\/figure>\n\n\n\n

Make sure you check that box if you want the conditional forwards to replicate to all your other DNS servers.<\/p>\n\n\n\n

Now the conditional forward works<\/h3>\n\n\n\n

Now you\u2019re DNS should be able to resolve your website under the subdomain www.<\/p>\n\n\n\n

I still feel like this was easier in the past but this is how I got it working on a Windows Server 2019 DNS. So I thought it would be a good idea to document the process. I hope it has helped you!<\/p>\n\n\n\n

If you know of a better way please let me know in the\u00a0comments below<\/strong>! I\u2019d love to hear about it.<\/p>\n\n\n\n
