config setprop smbd status enabled
service smbd start
Those commands are doing two different things.
One is setting the start up status in the configuration db file, so that when sme server starts, smbd will not run (if disabled) or run (if enabled).
The other is actually telling a service to start or stop and it's obvious which one does what.
eg common scenarios
you can stop the service, but it will still start up again when sme server is rebooted (with status=enabled).
...and vice versa, you can start the service, but it will not restart after a reboot (with status=disabled).
