Static ip and static DNS

    My domain is at a windows 2003 native mode and 2003 forest mode. I have an
    AD integrated DNS zone that allows for secure DNS updates only. If a server
    is configured with a static ip address and static DNS settings, then when
    the server registers its ip address and name in DNS, then who owns the
    record? also because DHCP was not used to supply the server with an ip and
    DNS settings, then is the A record for the server in DNS subject to DNS
    scavenging? Do I need to make the A record static in DNS to avoid the record
    getting scavenged? a little confused on this particular topic

  2. hi sawyer, thanks for the post. the record is technically owned by the SYTEM
    account on the DNS server but i think what you are asking is who can make
    changes. fore secure only zones, a statically configured resource will
    register its own record and will therefore have rights to update that record.
    by default, there are other accounts which can manage all records including
    SYSTEM (which is what allows the DNS Server to scavenge the record) and
    standard enterprise administrative accounts like ENTERPRISE DOMAIN
    CONTROLLERS, Enterprise Admins, etc.

    Even though the IP address is configured statically, the DNS record is
    registered dynamically. this means that if aging is configured for the zone,
    and any DNS server is configured for scavenging which owns that zone, the
    record will be aged and scavenged.

    For more detailed information:

  3. A little further clarity for Sawyer on scanvenging.

    Any dns record that was statically entered (By default) will not be
    scavenged. You have to go to the specific host record (A) and check the
    scavenge option. This option only becomes visible when you are in advanced
    view within the mmc dns console.
