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 => Ctrl-C to
shutdown server; call with --help for options

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. I submitted this to the Ruby
mailing list and Eric H. suggest I try the following:
U:\ruby>ruby -rsocket -e “TCPServer.new ‘localhost’, 3000”
which proved there’s nothing already running on port 3000. Any
suggestions would be gratfuly received.
