    Peter,
    I refer you again to the services file similar to:
    C:\WINNT\system32\drivers\etc\services
    The aliases for ports 137, 138, and 139 suggest that they are used for
    NetBios communications over TCP/IP. If you diable File and Printer
    Sharing, these ports will not be used, since File and Printer Sharing
    is done via NetBios (I believe from what I've read).
