Connection activation failed Device not managed by NetworkManager

After a fresh installation of Fedora 13, I encountered "Connection activation failed Device not managed by Network Manager". I have no ethernet connection.

Just like all RH users, I did a

# service network restart

And I go this error

It is only starting the Network Manager Manually, I got my ethernet connection

# /etc/init.d/NetworkManager start
