The network allows people at remotely located sites to communicate and share their ideas using common communication protocol. The main subject of this paper is to introduce a complete development environment for building a knowledge-based applications. It provides a step-by-step methodology knowledge engineering using TCP/IP protocol. Since the cost and performance of the application depend directly on the quality of the knowledge acquired, this tool reduces cost and improves the quality by letting domain experts to build the knowledge base file directly without needing to the knowledge engineer. for more information please visit your website : University of Babylon (en.uobabylon.edu.iq/nt/)
