2) The Domain Controllers (DC1 and DC2) and the Centos_5 are in LAN 1
- LAN 1:
- The IP of Centos_5 is ""
- DC1 is ""
- DC1 and Centos_5 can ping each other by its IP addresses

3) My Goal:
- I want to configure the DNS server for Centos_5 (the DNS server or name server are the IP of DC1 and DC2 ( and

4) At Centos_5
- Login as root
- cd /etc
- [root@Centols_5 etc]#
- Type in: gedit resolv.conf
- The error messages:

xlib: connection to ":0.0" refused by server
xlib: no protocol specified

cannot open display:
Run 'gedit --help' to see a full list of available command line options
