I had configured my LAN setting.
but my DNS Server automatically changes to "127.0.0.1" after restarting computer.
in the file "/etc/resolve.conf"
Code:
search iitd.ac.in local
nameserver 127.0.0.1
nameserver 10.10.1.2
nameserver 10.10.2.2
the line containing "nameserver 127.0.0.1" reappears automatically

after shutting down computer i saw the message
mDNSResponder Service [FAILED]
plz give anu suggestion
thanks for help in advance
