  • second domain controller

    newbie to server
    i have scoured the web and am getting conflicting information, do i need to add the second dc to the domain before running dcpromo, also will the second dc be a like for like copy of the first so if a goes off be will take over

    I generally do add to the domain first - I don't think it is required, though
    Yes, in AD all DCs are equal* so if one is not available another will take over. Assuming DNS is on the DCs, DNS will be replicated as well

    *I'm not going into FSMOs here - that is a lengthy piece of research in its own right.

        You can't replicate an entire DHCP scope between servers. Try configuring a split scope instead.
