Ubuntu 12.04 Reset Empty/etc/resolv.conf nameserver settings how to solve

The company's new server is using the latest Ubuntu 12.04, colleagues and I reflect a problem, after each reboot,/etc/resolv.conf inside the set nameserver was emptied, very strange

root@ttpod:~# cat/etc/resolv.conf  
# Dynamic resolv.conf (5) file for glibc resolver (3) generated by resolvconf (8) 
  
   # do don't     EDIT this FILE by HAND-YOUR CHANGES'll be overwritten 
root@ttpod:~#
  

Take a closer look and find the problem

Don't EDIT this FILE by HAND-YOUR CHANGES would be overwritten

Do not edit this file manually, the changes you make will be overwritten.

Do not know is this translation, I am relatively rotten e-wen, understand this meaning.

We change DNS generally is here to change, I used Redhat.

In order to prevent the system reboot, the DNS settings are emptied, we want to change the configuration file of the NIC

root@ttpod:~# cat/etc/network/interfaces  
# This file describes the network interfaces available on your system 
# And how to activate them. For more information, interfaces (5). 
     
# The Loopback network interface
Auto lo 
iface lo inet Loopback 
     
# The Primary network interface
Auto eth0< C8/>iface eth0 inet Static address
192.168.0.2
netmask 255.255.255.0
Gateway 192.168.0.1
Dns-nameservers 192.168.0.1

Add Dns-nameservers dns_address to the inside.

Reboot again, and it won't be emptied.
