(VIrtual NEtworking System) An earlier Unix System V-based network operating system from Banyan Systems that ran on DOS and OS/2-based servers. It provided internetworking of PCs, minis, mainframes and other computer resources providing information sharing across organizations of unlimited size. Incorporating mainframe-like security with a global directory service called Streettalk, VINES allowed access to all network users and resources. Options included printer sharing, e-mail, remote PC dial-in, bridges and gateways. See ePresence.
