Hey, I don't know if you already got an answer to this question, but you can check your samba status thusly:
$[sudo] /etc/init.d/smb status
NB! the square brackets around "sudo" means you either use "sudo" or you are already logged in as root (must have root/admin level access to do this). When you're logged in as root, your prompt will usually be a "pound/hash" (#) instead of a "dollar" ($).
If you use "stop", "start" or "restart" you can stop, start or restart samba. Also, you must have at least nmbd running, so while you're at it, put "nmb" or "winbind" instead of "smb" in the above command, and you will have the nmb or winbind status.
