How to Create Active Directory Sites and Subnets | Windows Server 2019

New Video Series on Managing Active Directory Environment:

In this video guide we will take a look at the steps to Create Active Directory Sites and Subnets in Windows Server 2019.

Topics Covered in this video:

1. Creating Active Directory Sites
2. Creating Subnet associated to the AD Sites
3. Move Domain controllers to appropriate AD site
4. Check replication after moving server to the AD Site.

I had forgotten how to do this and your video helped refresh my memory.
Thank you!

AD Sites and Services
We have multiple stores across the country. Each store has a site in AD and has a connection to our HQ.

We are removing all our DC's from our Primary Data Center HQ (basically shutting down). We have Created new DC's in Azure and moved FSMO roles etc. There is connectivity set up between retail stores and Azure.

Sites and Services

Before we completely remove all the DC's. We need to make sure all the retail 50 stores that are pointing to our Data center, we need to change it to point to Azure.

Two questions:

In inter-site transports - IP, we have over 50 site link created, we would have to remove the Primary Datacenter HQ and add Azure - is this correct?

In Each site for Existing DC's we have an automatic connection established with HQ, will we have to create a manual connection to Azure?

If we remove HQ, will KCC automatically create a connection or we will have to manually create connection to Azure?


Any other thing that we have to keep in Mind?

Can we rename the PR DC site during working hrs and create DR site than add the subnets does going to impact DC's

​ @MSFTWebCast, Brother to me this subnet issue can be resolved easily, if we create this setup in Azure Cloud by taking either different regions for Sites DCs or by taking different VNets for Sites DCs...in that case we can deal with different CIDRs for sites...but even then we will still need R&R access server or VM for communication between the sites....???

How can I create subnet in virtualbox. the one you did.

[martinephilippe]

what do you do for sites that are related by permanent vpn and have no ip but a lot of subnets?

I'm having the same issue as some of the other people. I have 2 network segments. A 192 and a 172. My 2 DC's are currently in my 192 and when I standup a new server in my 172 I cannot authenticate to it to join the domain. I full traffic from and to both subnets and can see everything just fine. I've even disabled the firewalls temporarily on my DC's to make sure that wasn't the issue. But even so I've had no success. Any ideas what may be causing the authentication to fail for new machines on the 172?

Hi, I have a question. Our enterprise has two offices, we configured a site2site vpn between the two offices. But in the headquarters there are too many subnets and lots of VLANs. In the secondary office, only has one subnet. Now the 2 DC has in one AD Site, but I want to make 2 sites and separate in a different subnets. Can I define just the secondary office sites, and then the primary office uses the default site and the remainder subnet sets, which is not definied? Thank you

Once this is set up, how can you create a DNS record that points to different IPs depending on which site the workstation is a member of?

[alwu]

what would be the reason for servers not showing in site and services? connection was checked no fault...

[rutujasalunkhe]

In my parent server machine there is no option for new site...What I have done wrong ... please rectify

Great video can you give me next video link as you told in the end of the video? Thanks

Nice accent u got there. Rly had to turn on subtitles. Thx for helping me out tho

[Ms.Robot.]

Problem: how can they replicate if they exist on different subnet segments? I tried. It will not let me setup replication to a different subnet.

[HisLoveArmy]

So as of now mine is empty and we have been running this AD for over ten years. Should I go ahead and add in our IP network? Will it break anything?
