This message

     Dec  2 17:03:15 ettelbruck named[1762]: [ID 295310 daemon.warning]
       owner name "gc._msdcs.luxair" IN (primary) is invalid -
       proceeding anyway

is a warning message about the "_" character.  You can eliminate the
message by adding the option

     check-names slave ignore;

to your named.conf file.  BIND 9 does not check for underscores.

This message

     Dec  2 17:15:39 ettelbruck named[1762]: [ID 295310 daemon.error]
       error processing update packet (NXRRSET) id 276 from
       [172.21.3.100].2819

means, I believe, that in the DDNS packet sent to the master server
there was a pre-requisite that was not satisfied.  (See RFC 2136,
where NXRRSET is defined as "Some RRset that ought to exist, does not
exist.")  Because the pre-requisite condition was not met, the DDNS
update was not performed.
