In context he doubtless was referring to the System Message Block protocol
that IIRC was first implemented in OS/2 LAN Manager and was continued into
Windows with all kinds of changes over the years. It is still in use, and
is (mostly) how your Windows desktop deals with file and printer sharing.
Samba is an implementation of SMB for UNIXy systems. IBM had an independent
implementation of SMB in z/OS, but has dropped it in favour of NFS.
