Terminal Services and Multiple Sessionsw

Terminal Services refers to the support in Windows for multiple interactive user sessions on a single system. With Windows Terminal Services, a remote user can establish a session on another machine, log in, and run applications on the server. The server transmits the graphical user interface to the client, and the client transmits the user's input back to the server. (This is different than X windows on UNIX systems, which permit running individual applications on a server system with the display remoted to the client, because the entire user session is remoted, not just a single application.)

The first login session at the physical console of the machine is considered the console session, or session zero. Additional sessions can be created through the use of the remote desktop connection program (Mstsc.exe) or on Windows XP systems through the use of fast user switching (described later).

Windows XP Professional permits a single remote user to connect to the machine, but if someone is logged in at the console, the workstation is locked (that is, someone can be using the system either locally or remotely, but not at the same time).
