Antwort: Domain controller unable to dynamically add/update PTR record

[holger.honert at signal-iduna.de]

One advantage (is ist really?) of QIP DNS is the multiple master 
architecture. have you something like this? If so, then keep in mind that 
updates to other qip-dns servers are made via prerequisites 
using something like "QIPBogus.Domain". 
Maybe that's the problem, thus you have to check your QIP-Design. 

Else, I don't really know that if w2k dcs use prereqs. To my mind the w2ks 
use only "update delete dcserver.domain.com in a" followed by "update add 
dcserver.domain.com 12345 in a 1.2.3.4" unless
you change the value in the registry for the automatic deletion!

Thema:        Domain controller unable to dynamically add/update PTR 
record


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 128.244.198.27#2772:
updating zone '
dom1.jhuapl.edu/IN': update failed: 'RRset exists (value dependent)'
prerequisit
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.

Thanks,

Bill
