Hello,

We have couple of Windows Server 2008 R2 Domain Controller in my Domain, out of which one DC is failed & we unable to bring it back to the network.

I came to know some articles where it has been stated to delete the DC object directly from ADUC & ADSS. I just want to understand what are the right steps to follow so we can remove the failed DC with no metadata footprint.

Thanks.

    Hi

    Make sure that DC is offline, and will stay offline first.

    After that you can delete the computer account from the ADUC's console, it will prompt you a message, that if you forcelly remove it, say yes. It will remove reference to it from ntdsutil.

    You will need to clean the DNS's zone afterhand, as some entry might still reference it.

    Make sure your DHCP no longer give that DC IP.

    Except that, it should be clean after.

    Thanks
