is it possible to join a win 10 or 11 machine to a ADDC VM on azure

Question

I have created an VM on azure with server 2019 operating system and configured the AD DC on it but when I wants to join a win 10 or 11 machine to domain on this VM it does not work and keep saying that domain controller cannot be connected and showing some DNS error. Regards OS

Answer 1

Yes - you can. You need to ensure that you modify the default DNS configuration within the Azure VNet environment. The simplest way to do this is to assign the custom DNS IP address in the virtual network properties in the Azure portal (assuming that the Windows client VM is connected to the same Azure virtual network as the VM hosting the domain controller). Pls keep in mind that the Windows client virtual machine must be able to reach the domain controller via its private IP address, so it has to be either on the same Azure virtual network or another network connected to it.

Answer 2

To configure a custom DNS server in a virtual network (which should be set to the IP address of the Azure VM running the domain controller), follow https://learn.microsoft.com/en-us/azure/virtual-network/manage-virtual-network#change-dns-servers . For this change to take effect, you need to restart all Azure VMs connected to the virtual network.
