A DNS server which is supposed to be authoritative for a zone, but isnt.

If you see something like this

Aug 7 00:57:37 colo named[827?: lame server resolving '98.96-27.40.119.62.in-addr.arpa' (in '96-27.40.119.62.in-addr.arpa'?): 62.119.40.115#53

in your BIND logs, then BIND has queried a lame server. In this case, 62.119.40.115 is mentioned as being authoritative somewhere for the zone 98.96-27.40.119.62.in-addr.arpa, but when BIND queries it, it discovers that 62.119.40.115 is not authoritative, and logs that message. The SysAdmin at the other end needs to get a clue and fix his DNS.
