TelnetConsole crashing?

I generally use a TelnetConsole to connect remotely to the server so I can shutdown cleanly with a console "quit();" as opposed to an O/S level process termination. However I've noticed recently that after a day or so sometimes my TelnetConsole connection closes for no reason (i.e. no client or server activity at all for the last few hours) and thereafter no longer accepts any connections on that port, even though I've confirmed that the game process is still running on the server. At this point the only thing I can think of to get my console back is terminate the game server at the O/S level and restart it. Are there any alternatives if/when it comes to this?

Has anyone else seen this problem with TelnetConsole? Is there any way to reset the TelnetConsole from the O/S (which is windows server 2003) somehow?
