My rule for this issue is to remove network manager.

On two desktop computers with static IP addresses was.

-install F10 from DVD.
-apply all the updates.
-install yumex.  {I like it better than packagekit}
-install system-config-network
-turn off networkmanager
-remove networkmanager
-run system-config-network
-enter in settings
-restart networking
-ensure networking is running properly
-test by rebooting.

As others have suggested, check /etc/sysconfig/network*
as well as /etc/resolve.conf
