Hello every body, I just started working on Ruby on Rails and as i am
progressing I noticed that I can not start my WEBrick server on the
Command prompt. The following are the various error messages that I am
going.

Please i will be very happy if i receive a reply. thank you all.
It means you already have something, probably another instance of
webrick, listening on that port. Find it and shut it down before trying
to start a new instance.
There was a sudden power outage and therefore Webrick couldn't be
shutdown gracefully. On machine restart, I got the exact same error as
Gordons, however, my Ruby is 1.8.7 and I'm on a WinXP machine.
Additionally, I found that none of my browsers (IE/Firefox) can connect
to any website.
I would be thankful if you can explain step-by-step how to find out
whether another instance of Webrick is running and how to shut it down.
Of course, I tried browsing to 127.0.0.1:3000, but my browsers have been
affected, so the page cannot be displayed.
?! It's been years since I've touched a Windows machine, but that
sounds like your system is totally b0rk3d. Do you have a firewall
of some sort that might be affecting networking?
Try using basic networking tools like ping, traceroute, telnet, etc.;
if your system crash was extremely ungraceful, you might have an
OS reinstall ahead of you...
I had a hunch that reinstallation or trying a different port weren’t necessary. I probed a bit more and found some processes named netsession_win.exe in Task Manager. I stopped these. I then went on to uninstall some software named Akamai* from Add/Remove programs, and now all is well.
