"Disabled" (the red dot) means that the service will not be started on next 
boot. "Running" (the plug) means that the service is currently active.

Those are two separate concepts, you should never confuse them.

The password is asked on your first attempt to change something, and 
authorization lasts until some reasonable timeout (couple of minutes or so, I 
don't know exactly). This is if you use GUI. If you use the "service" command 
in the terminal, there is no pop-up window, you should be logged in as root 
instead.

Are you not being asked for the root password?

chkconfig iptables off

Be warned though, that not running a firewall is a Very Bad Idea if the 
machine is connected to the Internet. If you have trouble with samba, I 
suggest configuring the firewall appropriately, rather than disabling it 
completely.

No, everything is working as expected. The "service" command does what it is 
intended to do --- start or stop the service. This has of course nothing to do 
with configuring what will happen at next boot.

The "chkconfig" command configures what services will or will not be started 
at boot.

Could it be that these are the root password requests that you were asked for 
while playing with the services GUI? If I understood your comments above, the 
services GUI failed to ask you for a root password, right? And now you find a 
bunch of password requests waiting somewhere else, right?

It might be that your desktop environment has something screwed up and the 
pop-up requests do not appear on the same desktop as the originating app. 
IIRC, this is configurable somewhere, depending on the DE you use.
 
HTH, :-)
