    Hey man….
    Thanks for the video…
    3:30 …. my DNS configuration is ok… AD is hosted on and i want to install child domain on….. but i cant ping the DNS / DC from would be child domain….How did you ping the DC from different network ? Because, as per your setup you used (AD+DNS) 172.X.X.X and (FRESH SERVER) 192.X.X.X both are in different network and also different subnet. So, without setup any ROUTE , how could you ping one another ? I am pretty confused about it.

    Thanks so much for your video.I didn’t get to see the forward look up zone "mylab.local" in the root dns server.1. Does it exists? If yes, this brings me to the second question. 2.Assuming you have "mylab.local" as your external Domain and collins.mylab.local in your external dns server (A record) but it does not exist in the internal dns server. As a result internal users can’t resolve "collins.mylab.local from the internal

    Hi, thanks for your great videos, I just created a child domain step by step, now it’s done and every thing looks fine in child domain site(I can resolve addresses of child and parent domain), but on the parent domain in DNS forward zone I can see a folder with the name of my child domain but nothing in it! that’s why I can’t resolve child domain address in the parent domain, any solution? thanks for your help.

    Hello friend, can i ask you? If my root domain is named as svk.testdomain.local and i want to create a child domain(cz.testdomain.local). Is it possible? Or is possible only cz.svk.testdomain.local? How it looks in video in time 5:45 for parent domain? svk.testdomain.local or only testdomain.local?
