First message indicates that the client 120.130.33.17 is trying to do a dynamic update to the zone stone.com.tw and failed because a rr record already exists or the client is not allowed to do a dyanamic update . Is this client is in ur network ? . R u using dynamic updates for ur dns server ?

The second message ( lame server resolving ) indicates that named has learned from a
nameserver that a particular domain is served by a particular
nameserver. When asked, however, that nameserver denies all
knowledge of the particular domain. This means that the server is not an authoritive server for the domain 'conmart.co.tl' .

Does it an error message such as "lame server resolving" ? thanks in advanced.

[Bejoy C Alias]

No. it is not considered as an err message, its just a warning.

[j773303]

Is it possbile let syslog.log don't such ttat message ? Thanks in advanced.

U can use the logging option in named.conf to discard the lame server messages . Add the following to the named.conf file .
logging {
category lame-servers {
null;
};
};

This will log the messages of category lame-servers to the channel null , which will actually log that messages nowhere.
