Windows NT 4.0 Terminal Server Edition (codenamed Hydra) is an edition of Windows NT 4.0 released on 16 June 1998, which allows remote solutions to applications on a server. Microsoft licensed the Terminal Server technologies from Citrix Systems, which already released a similar solution using Windows NT 3.51 Server under the name of "WinFrame". The Terminal Server Edition was dropped with the release of Windows 2000 in favor of Terminal Services being integrated to the Server Family.
