Error Processing Update Packet (NXRRSET) Message

[Smith, William E., Jr.]

I'm seeing the following error logged to my messages file:

Feb 8 12:32:51 dnservername.site.edu named[424]: error processing update
packet (NX
RRSET) id 18 from [10.0.0.1].1091

Looking at the db.log for the domain the object is trying to be added to, I
see lines such as this:

[DYNAMIC_UPDATE] id 70 from [10.0.0.1].1426 at 981661079 (named pid 424):
zone: origin subdomain.site.edu class IN serial 56
prereq: {nxrrset} host.subdomain.site.edu. IN CNAME
prereq: {nxrrset} host.subdomain.site.edu. IN A
update: {add} host.subdomain.site.edu. 1200 IN A 10.0.0.1

I've the archives and found some info which basically stated a prereq was
that the host not own any CNAME/A records. As far as I can tell & see, the
object doesn't own any other CNAME/A records. Interestingly enough, the PTR
record seems to get in just fine.

Just as FYI, I'm testing a W2K client with the "register connection in DNS
box checked". I initially got errors about unapproved updates but I quickly
fixed those so my test client could perform the update. With all the
necessary privileges in place, I then got the errors above.

I'm banging my head against the wall trying to figure this one out but must
be missing something. Any help would be appreciated!

Thanks,

The Dynamic Update attempt which caused that event to be syslogged was not the
same as the one which caused the entry in the db.log file. Note that the source
ports are different. I believe Win2K sometimes just sends "probe" updates
(prereqs without any actual update) prior to making an actual update. That's
probably what you're seeing. It's not really an "error" _per_se_. So you can
stop beating your head against the wall.
