title: I can't open tomcat
body: <p>I'm using Tomcat 5.5 on Windows Vista. When I exit my tomcat, I can't run it again. </p>
  
  <blockquote>
    <p>Access is denied. Unable to open the
    service 'Tomcat5'</p>
  </blockquote>
  
  <p>Why is that so? What can I do to make it work again? Must I reinstall everytime I exit tomcat?</p>
