How to Add a Child Domain to an Existing Forest | windows server 2019

[@gbbal65]

Thanks your work! It helps a lot!

Should the conditional forwarder also go on the primary DC for the root domain?

[@FranzGuerrero]

Thank you for the video. I tried first, but didn't work, I was not able to ping, then I started reading the comments below from asaduzza, and this setting requires LAN routing on a separate server with two NIC's to attach these networks together. After the installation of the Lan routing and adding the rule on the firewall on the separate server, I was able to connect and ping the two networks It requires a little challenge. appreciate you help on posting the videos.

You are the Best. Bravo.

Thank You.

[@harshalsaraf9473]

just a question, in your videos, could you please explain what is Active directory sites & services used for and why we need to create a subnet etc. Please explain.

[@MSFTWebCast]

I feel I am not good at explaining things. So I try to keep it short. Suppose your company has multiple domain controller located at different geographical locations. In that kind of scenario we need to define the physical location in Active Directory as a AD site and to define associated IP network, we have to use IP subnet in AD Site.

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 network.

Thanks peter, I hardly get positive comment about my accent. You sure, is it positive?

Can you see all ADUC and Group policies for all child domains/DCs from the forest root?

[@funcat7035]

How did you configure your network card settings ? I am unable to work out when creating different subnets unable to ping virtual machine

[@MSFTWebCast]

I have used one more VM with two NIC's. I have configured LAN routing on it to use that VM as a router. There is video for the same on my channel.

[@Derisoireetsardonique]

as to the reverse lookup zone, the prefix seems to be assuming that you are using a /24 network, however what would be the prefix if your network is /21 or /28 ?

[@MSFTWebCast]

There is a way to create reverse lookup zone with classless IP address range but I haven't tried ever. Generally I used to create multiple reverse lookup zone as per my network blocks. If required we can leave octet blank in network id section. But after your comment I would love to test this.

Hello Dear, to create adc,cdc,gcdc does it need to buy new server? or it can be created on single physical server using hyper v or vmware. because cdc is used to create to increase branch of company and if we have another office in delhi so we have to buy new server and link with existing root domain. please help

[@DigiTechTools]

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.

[@asaduzzamanjony6243]

Hey man.... Thanks for the video... 3:30 .... my DNS configuration is ok... AD is hosted on 192.168.50.60 and i want to install child domain on 172.168.50.60..... 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.

[@MSFTWebCast]

Sorry I did not cover that part in video. I have used one windows server 2019 VM as an router to connect two different network.

[@asaduzzamanjony6243]

@@MSFTWebCast Thanks for your reply :) Yes i saw that tutorial in your website :D .. So i need to use a VM between these 2 VM... and the middle one will have 2 interfaces, one connected with my AD and another with Child AD . Overall, that will act like a router establishing route between 192.X.X.X and 172.X.X.X ... ... Right ?

Hi, Thanks for your videos. I have an issue with the child domain. I followed all steps, but I have a computer in child domain witch can't ping the parent domain controller, so it can't reach my SQL server located in this parent DC. Do you have an idea about the source of this issue? or if you have a troubleshooting guide to follow? Thanks one again.0

[@MSFTWebCast]

Is client pc (in child domain) can ping using IP?

[@pg4694]

why there is need to create new site fo cdc is it compulsary to do that

[@MSFTWebCast]

Generally it helps in replication optimization. If your domain controllers are placed in different geographic location, you can create AD site to represent those location in AD replication topology using AD site.

[@pg4694]

I really was unable to understand 1.why there was a use to create a new sir and provide subnet it has just made the video lengthy 2.when you created CRC and made change to preferred I'd and provided root domain up in the CDC preferred dns server then why there is need of conditional forwarding unnecessary is it required or mandate 3.when CDC and root domain has different database why replication is required like what exactly is replicated 4. What kind of access users have on each other like can they log in on both the domain or only the admin

[@MSFTWebCast]

I think first you need to understand the fundamentals of Active Directory Domains, root domain, child domain, AD replication as well as DNS name resolution process.

How to configurate dhcp in child domain. I have a problem with autorization dhcp on server DC in child domain.

[@MSFTWebCast]

You can ask any of root domain admin to do that for you. Or use this link for other way around. social.technet.microsoft.com/wiki/contents/articles/14456.windows-server-authorize-dhcp-server-without-enterprise-admin-privileges.aspx

why slash 24 after the ip address can u please tll ho u calculated 24 after / and as per my knwldg 192 is c class ip address which has three network and one host so how the value after slash is 24 pleae let me know

[@MSFTWebCast]

I used /24 to specify the network of that specific Active Directory site.

Sir, root domain me new site create kaise aur kab karate hai plz bataye

[@MSFTWebCast]

If you domain controllers place in different (physical) locations than to define it in active directory, we create AD site. The AD site will store the domain controller from one specific location with the IP addressing information which you define using IP subnet.

I am not able to resolve my root domain from child domain dc can anyone help me with this

Good

[@actandrepeat]

So the mylab.local. and the delhi.mylab.local. are now effectively called a tree in a forest, right?

[@MSFTWebCast]

delhi.mylab.local is a child domain and mylab.local is a parent (root) domain.
