If the DC goes down with a single domain controller, you cannot manage or log in to the domain. It is always a best practice to install at least two DCs. If you are using VMs for your DCs, you should also ensure that each DC VM is on a separate virtualization host – otherwise, the VM host is a single point of failure.

To add a second DC to your domain, you run Install-ADDSDomainController on another host, that is DC2. This cmdlet is similar to Install-ADDSForest in terms of parameters. It is useful to conduct tests to ensure the second DC’s promotion can succeed as with creating your first DC.

In this recipe, you promote a host, DC2, to be the second DC in the Reskit.Org domain. Like creating your first DC, after you promote DC2 to be a DC, you need to reboot the server before...
