I am new to Ruby so I thought the best way to get into it would be to  
follow the ONLamp “Rolling with Ruby on Rails” intro. I followed the  
instructions to the letter and everything work just great, very  
impressive:-).

A couple of days later when I went back to it I got the following  
message when trying to start the WEBrick server.

U:\RoRProjects\cookbook\>ruby script\server

=\> Booting WEBrick…

=\> Rails application started on [http://0.0.0.0:3000](http://0.0.0.0:3000)

I have tried totally uninstalling (ruby, rails, MySQL) and then  
reinstalling but with no success. Obviously something has changed in the  
environment that it is running in but I cannot recall anything that has  
been done that would be of significance. Any ideas what could cause  
this?

Any assistance would be gratefully received.

Regards

Brian Watson

You probably have a WEBrick already running. Shut it down.
