If someone remoted in as console mode, then the application crashed. There was a bug in the application that required it be run in the console session. One application that I administered would crash if anyone logged into the server in console mode. There is a small degree of risk associated with using console mode when remoting to a server. This isn’t the case when a session is opened in nonconsole mode. The advantage of opening a session in console mode is that any applications that are currently running on the server will be visible to the console-mode session. This is also referred to as “session 0.” You can connect to this session by adding the parameter / console when making the connection from RDC. A session, called the console session, always exists on the server. When using RDC to connect to a remote Windows server, you are effectively creating a new session and logging into it.
