Check your /etc/host.conf file to make sure that it contains something
like:

order hosts, bind
multi on

or if you have NO namedaemon support, just

order hosts
multi on

This file is used to determine which resources, in which order, are
used to resolve names.  Also check your resolv.conf and learn
something about NIS -- two other possible candidates.  For example,
you could be using NIS and named to resolve names but not have remade
your NIS map after altering /etc/hosts.
