In our environment, we have allowed Windows domain controllers to
dynamically update their A & PTR records within the Windows only
domains. I'm currently troubelshooting a problem where a couple DC's
register their A records fine but fail when trying to do their PTR
records. After sifting through the various server logs, I came across
the following error which I believe is at the core of the problem since
I had a Windows admin do an ipconfig /registerdns on the DC to force it
to re-register its records and noted that this error appeared within
seconds after that attempt.
update.log:Jan 24 11:45:24.901 info: client 188.8.131.52#2772:
updating zone '
dom1.jhuapl.edu/IN': update failed: 'RRset exists (value dependent)'
e not satisfied (NXRRSET)
While it's clear that the problem is related to a prerequisite not being
met, it's not clear to me what exact prerequisite has failed to be
satisifed. Can anyone shed any light here? I know this is a common
problem with DHCP clients but DHCP is not involved here. FWIW, the
primary DNS server where these updates are coming into is a QIP DNS
server. I'll provide any further info as needed/requested.
