How to replicate a Domain Controller

categories

In this tutorial, you will learn how to replicate your on-premise Domain Controller in the cloud. This is very useful to avoid any possible service interruption in case your on-prem Domain Controller is unreachable. Your system will be fully redundant this way and you will be prepared for every scenario.

STEP 1

Create a VM that you will promote to Domain Controller. You can follow this tutorial to create your VM.

STEP 2

Ask V2 Cloud support to put all your new VMs on the same network as your others, enable File and printer sharing in Firewall and change SID number. You can contact them via the online chat in your Dashboard or at [email protected]

STEP 3

Check if NLA is disabled for all your VMs. Uncheck “Allow connections only from computers running Remote Desktop with Network Level Authentication” in System –> Remote settings.

mstsc /admin-command

Promote your new VM to a Domain Controller that you will Add to an existing Domain Controller. A reboot will be required.

NOTE : In order to be able to connect with the administrator, both OS Domain Controller Administrator passwords need to be the same. Here is how to change the password.

Add the VM to the existing domain first. You can follow this complete tutorial to join a VM to your domain.
