multiuser NT

Using Windows NT like a central, timeshared computer with terminals. Citrix developed this method with its WinFrame software and subsequently worked with Microsoft to create Windows Terminal Server. As a network operating system (NOS), NT was designed to service many users; however, multiuser NT referred to a terminal-based architecture. See WinFrame.


Earlier software from Citrix that turned a Windows NT 3.51 server into a centralized, multiuser computer. Introduced in 1995, Windows applications were run on the server and only screen changes were sent to the client machines. WinFrame included a copy of NT 3.51 integrated with Citrix's MultiWin multiuser technology and the company's ICA presentation protocol. MultiWin was also licensed by Microsoft as the foundation for its own multiuser functionality (see Terminal Services). See ICA.

Windows NT and MultiWin
WinFrame was made up of a licensed version of Windows NT 3.51 and Citrix's MultiWin. Using the ICA protocol, it sent input from the client machine to the server and sent only screen changes back to the client.
