But since we're chiefly talking about Windows networking, SMB's origins (e.g. LAN manager) typically used other protocols (NetBEUI, for instance) long before it was run over TCP/IP. Microsoft's use of TCP/IP with their systems on a LAN was a later thing. It was quite some time after Win95's birth before TCP/IP would become the usual protocol underneath SMB (at that stage, TCP/IP was still a user-configured add-on). Even if you installed file sharing, it would be yet another user-choice to use TCP/IP instead of another protocol. I missed out on making it more clear I'm talking about SMB on a LAN, and Microsoft Windows LANs, not just LANs. i.e. Windows networking. But I was talking about the "origins of "SMB," not the origins of LANs. And back then, TCP/IP wasn't what they were usually using. It was quite typical for your Windows networking to be done all over a NetBEUI protocol. And if you also wanted internet, you'd do that separately over TCP/IP. SMB seemed to work much better over NetBEUI (none of this "can't find the other machine" hassles), and you isolated your LAN traffic from internet traffic more (NetBEUI doesn't traverse a subnet), so you couldn't accidentally share your drive over the net. > Also SMB is a file serving process or protocol, not a networking > protocol which TCP/IP is.
