FastCon is a donnationware utility that provides a remote console facility. I quote the author, Martin DEVERA:

FastCon is WinNT remote console service. It allows you to connect to the NT Server or NT Workstation remotely from a WinNT or Win95 system.
Very nice thing is that you can disconnect from running session (either by line error or Ctrl-BREAK signal) and the remote session is still running. You then can latter reconnect to the session and continue with work.

This is a great remote console utility, so do the right thing if you continue to use it.

Note: After establishing a remote session using fclient ServerName new SessionName,
you connect to it using fclient ServerName con SessionName.
