[Leaplist] Still can't get online

[William H. Ferguson]

My Main Desktop Computer has suddenly ceased to be able to get online.

So, now, I'm using a second computer whose e-mail program and ability to 
get online is OK.

A friend suggested I try these commands as root on my Main Desktop Computer:
cd /etc
cd  init.d/

"root at localhost init.d]# ./network restart "

Here's the response:
"Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0:
Determining IP information for eth0...cp: cannot remove 
`/etc/resolv.conf.predhclient.eth0': Permission denied
done. "

Does this suggest to any one how I can "fix" my inability to go online?

Thank you for any guidance.

William
