+<emphasis>ANSWER:</emphasis> Samba consists on three core programs:
+<emphasis>nmbd, smbd, winbindd</emphasis>. <command>nmbd</command> is the name server message daemon,
+<command>smbd</command> is the server message daemon, <command>winbind</command> is the daemon that
+handles communication with Domain Controllers.
+</para>
+
+<para>
+If your system is NOT running as a WINS server, then there will be one (1) single instance of
+ <command>nmbd</command> running on your system. If it is running as a WINS server then there will be
+two (2) instances - one to handle the WINS requests.
+</para>
+
+<para>
+<command>smbd</command> handles ALL connection requests and then spawns a new process for each client
+connection made. That is why you are seeing so many of them, one (1) per client connection.
+</para>
+
+<para>
+<command>winbindd</command> will run as one or two daemons, depending on whether or not it is being
+run in "split mode" (in which case there will be two instances).
