Some users are unable to connect to specific local hosts by name, while accessing hosts in other
zones works as expected. Given that the hosts are reachable by their IP addresses, which is the
default log file that could provide hints about the problem?

A.
/var/named/log

B.
/var/lib/named/dev/log

C.
/var/log/bind_errors

D.
/var/log/bind/errors

E.
/var/log/messages

Explanation:
BIND uses syslogd before a valid logging clause is available so named.conf parse errors and other
information will appear in /var/log/messages (depending on syslog.conf) prior to, or in the absence
of, a valid logging clause.
On Ubuntu Systems this is equal to /var/log/syslog.
