    moving my physical domain controller to vmware machine and stuck. . .

    Hello everyone,

    I have a server running windows server 2012 running as my domain controller. I installed ESXI 5.5 on a server, and then created a virtual machine through VSphere installing server 2012.

    I gave the server a static IP, and set the primary DNS to the DNS of my other domain controller.

    Then I added the active directory and dns roles.

    The internet works fine.

    Now I am trying to promote to domain controller and keep getting error: "Verification of replica failed: Failed to examine the Active Directory forest. The error was: ridmasterserver.dnshostname failed."

    I am doing this for experimentation as I am new to administering windows and domains, so any help is appreciated.

    Thank you

    You're keeping at least one physical dc right?

    Why not just use VMWare converter and convert your physical machine to a Virtual on ESXI ?

    Interesting... I was having a conversation with someone who knows far more about this than I do, and he was suggesting that it's fine to run virtual DCs - it's not best practice to run them on the same host. He did however say that it was not possible to P2V a DC as some of the DC roles are tied to the hardware and will fail to work?

    I'm not sure that its tied to the hardware per se, but I'd agree that its very bad practice to P2V a DC. Windows domains should have more than one DC present anyway and it doesn't add that much time to demote a DC then promote it again either side of your P2V process.

    I tried to do this but the drives on my physical DC have a size of 800GB (only 200GB in use), and my drives on my NAS is only 1TB with other info on it, so it was erroring out on me
