    If it isn't a firewall problem it is likely a
    DNS issue (or DNS due to firewall etc.)

    Start by checking DNS and running DCDiag
    on the existing DCs. Then go to the new-to-be-DC
    and use NSlookup (or similar) to prove you can
    contact the existing DNS.

    DNS for AD
    1) Dynamic for the zone supporting AD
    2) All internal DNS clients NIC\IP properties must specify SOLELY
    that internal, dynamic DNS server (set.)
    3) DCs and even DNS servers are DNS clients too -- see #2

    Restart NetLogon on any DC if you change any of the above that
    affects a DC and/or use:

    nltest /dsregdns /server:DC-ServerNameGoesHere

    Ensure that DNS zones/domains are fully replicated to all DNS
    servers for that (internal) zone/domain.
