Static ip and static DNS

Hello

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

Thanks

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.

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.
