    IMO, RPC itself is a protocol, but it's perfectly valid to refer
    to the RPC port, or service... I guess the problem is definitions.

    A protocol is similar to a language - a defined way for two programs
    to talk to each other. So there is an RPC protocol that defines how
    you talk RPC to another (Windows) computer.

    A port is similar to a TV channel - a program can choose which 'channel'
    it wants to use to communicate. The RPC program on Windows always uses
    the same port(s?) to communicate, so those are the RPC ports.

    A service is simply a program that runs on Windows, designed to perform
    a task - like a daemon on Unix. The file sharing service, the DNS
    lookup service, the contact Microsoft with your personal details service
    (heh heh)... so the RPC service is the program running that listens to
    the RPC port and implements the RPC protocol :)

    My guess would be mucking around with the hosts file...
