dns newbie - lame server

[Said Nurhussein]

Hello,
I'm new to dns and would like your help in understanding what the
following
error means, whether it is  useful to have on (see lots of msgs like it
in Solaris system messages file) , and how is it turned on/off:

-------------------------
Jun 22 13:57:48 ibis named[15488]: Lame server on 'ireland.fedstats.gov'
(in 'FE
DSTATS.gov'?): [198.6.1.82].53 'AUTH02.NS.UU.NET': learnt
(A=198.41.0.10,NS=192.
5.5.241)
-----------------------------

Also do you recommend any good dns documentation / tutorial site
for a beginner?

Thanks!
--Said.
