From time to time you may see "lame server resolving" entires in your log files. The problem results from doing a lookup on a domain, where the dns zone file is not listed as "authoritative" for the domain. The domain owner has to fix this.

However you can turn off the logging of these "lame server" messages so as to keep your logs clean. 

# vi /etc/named.conf

Add the following section....

logging {
category lame-servers { null; };
};

after your zone definitions.

Save and quit the file and restart named.
