Is it possible to connect a classic Macintosh to the Windows SMB network? Yes, but keep in mind the particular vintages of Macintosh under which this is possible. Obviously, support is skewed toward 1990s-era Macintoshes, typically those with the PowerPC processors, CD-ROM drives, color monitors, and so on. Connecting a black and white Macintosh to the Windows network may be much more tough luck.
