PDC registering itself in DNS on both subnets

Discussion in 'DNS Server' started by Andrew Hodgson, Aug 9, 2004.

  1. Hi,

    Have Windows SBS machine which is on (the server subnet)
    also acting as gateway for Have MS DNS server fully AD
    enabled listening on for LAN clients, and I have set up a
    third-party DNS server on which holds public DNS records
    for domains - this all works very well.

    However, an issue is that this machine is registering itself with the
    DNS server with both IP addresses thusly:

    hodgsonfamily.org. in a
    hodgsonfamily.org. in a
    elrond.hodgsonfamily.org. in a
    elrond.hodgsonfamily.org. in a

    This causes issues, as the clients on subnet are querying for AD records which are not present, attempting to do
    dynamic updates and worse are sometimes getting public IP addresses
    for servers which they shouldn't be getting.

    Is there any way round this? I first of all had everything hanging
    off the subnet, and the exact same thing happened, which
    was why I was told to change it over the above setup.

    Any help?

  2. Note that I have done some more discovery and have found that it is
    now only hodgsonfamily.org that is registering itself twice in the MS
    DNS server - so it turns out that creating a second subnet has helped.
    Will this cause any problems (the number of misfires in the public DNS
    logs have now diminished), and can I alter a setting to get rid of
    that extra A record?
