The Terminal Server service then calls the Windows NT Session Manager (Smss.exe) to create two (default = 2) idle client sessions (after creating the console session) that await client connections. The console session starts as a normal Windows NT system session with the configured Windows NT display, mouse, and keyboard drivers loaded. The console (Terminal Server keyboard, mouse, and video) session is always the first to load, and is treated as a special-case client connection and assigned SessionID. Each process created within a session is 'tagged' with the associated SessionID to differentiate its namespace from any other connection's namespace. Each connection is given a unique session identifier or 'SessionID' to represent an individual session to the Terminal Server.
