Network Control Program is the name for the software on the hosts attached to the ARPANET which implemented the protocol suite of the early ARPANET, Network Control Protocol as it later came to be called. (See here for more about the evolution of these names.) The term did not later, usually, include the applications (such as 'User Telnet').
