title: Rails server not working?
body: <p>I'm following the <a href="https://peepcode.com/products/meet-rails-3-i">first Ruby on Rails 3 tutorial</a> from <a href="https://peepcode.com/">PeepCode</a> and at around 27-29 minutes in, they have us start the Rails server. To the best of my knowledge, I have Rails (and Ruby) successfully installed.</p>
  
  <p>When I run the command <code>rails server</code> (from Windows 7 Command Prompt per the instructions of the video), I get the message:</p>
  
  <pre><code>=&gt; Booting WEBrick
  =&gt; Rails 3.1.3 application starting in development on http://0.0.0.0:3000
  =&gt; Call with -d to detach
  =&gt; Ctrl-C to shutdown server
  [2011-12-02 18:37:57] INFO WEBrick 1.3.1
  [2011-12-02 18:37:57] INFO ruby 1.9.3 (2011-10-30) [i386-mingw32]
  [2011-12-02 18:37:57] INFO WEBrick::HTTPServer#start: pid=5584 port=3000
  </code></pre>
  
  <p>And it doesn't return to the prompt, indicating that it is running. Also, to me (and compared to the video), this looks like a successful message.</p>
  
  <p>However, when I browse to the URL, <code>http://0.0.0.0:3000</code>, as directed by the video, I get an error (while the video opens to the default index page for Ruby). The error I get is:</p>
  
  <pre><code>Error 108 (net::ERR_ADDRESS_INVALID): Unknown error.
  </code></pre>
  
  <p>Since I'm using Google Chrome, it also says:</p>
  
  <blockquote>
    <p>The webpage at <a href="http://0.0.0.0:3000/">http://0.0.0.0:3000/</a> might be temporarily down or it may have moved permanently to a new web address.</p>
  </blockquote>
  
  <p>So, I was wondering how to fix this?</p>
