install centos

today,I continue to config company's server,I will build the asp.net environment easily if the 'yum' command is usable.

I want to fix this problem by make over /etc/resolv.conf file,the original nameserveres were modified to 8.8.8.8,and it's said i should restart the network service,but when i do it,the server appears to be a problem,'realink ...:file exist'

restart filed ,so i want to stop network service first ,and start next.

when i stop it,the tragedy occurred,my ssh client was disconnected,i suddenly remembered the ssh client client to the server by network service,if i stop the service,i can't continued to client the server

after that,to afraid of stopping server,i install centos at my vmware workstation in my computer,and now i'm trying to client the vm centos by ssh.
