Error Processing Update Packet (NXRRSET) Message

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.
