Try using netstat -aN to see if your computer is listening/established on port 23 on any interface

If it is then you can rule out your hardware although if not then the issue is hardware since its not running.
Also if you ave another computer to test with, you can get an outside IP address (perform this over WAN link, no LAN) and trying to access or port scan your computer on port 23 and seeing what happens.
