What makes you think that deleting host.conf was the right thing to do?

Host, nslookup, and dig use DNS automatically and exclusively, so there 
doesn't have to be any directive in the system telling them to do so. 
Most programs, however, use gethostbyname() etc. and need the 'bind' 
entry in host.conf, which you just removed by deleting this file.  If 
you restore the file DNS lookups will work.
