Phone Book Service is a Microsoft Internet Information Server (IIS) extension that runs on Windows NT Server version 4.0, with IIS version 4.0 running both the World Wide Web (WWW) and File Transfer Protocol (FTP) services. The WWW service allows the remote client’s computer to access the server, and the FTP service accepts updated phone book information posted from Phone Book Administrator.
The Phone Book Administrator allows you to create and edit multiple phone books. It runs on Windows NT Workstation version 4.0 or Windows NT Server version 4.0. The administration tool and server need a TCP/IP connection in order to post phone book information via FTP.
