HOW TO SOLVE - UBUNTU HOST (SERVER OR WORKSTATION ) NOT RESOLVING LAN HOSTNAMES

Even setting up the server name on file /etc/resolv.conf the issue  not solved ,
However was Necessary change this information on file:
vi /etc/nsswitch.conf
from: hosts: files mdns4_minimal [ NOTFOUND = return] dns

for:

#hosts : mdns4_minimal files [ NOTFOUND = return] dns
hosts: files mdns4_minimal dns [ NOTFOUND = return] mdns4

Obs . Normally in most cases the issue is fixed change the file /etc/resolv.conf add the
name server of your local network  or add hostname/FQDN/ip on / etc / hosts , However have cases that is not efficient, and this tip solved all my problems .
