title: CREDENTIAL_ERROR when starting Glassfish
body: <p>I am trying to Start Glassfish inside Eclipse when suddenly this message appear: </p>
  
  <blockquote>
    <p>The Eclipse plugin cannot communicate with Glassfish server, status
    is: CREDENTIAL_ERROR</p>
  </blockquote>
  
  <p>I have tried the solutions given here: Turn off firewall, turn off windows firewall, re-installing glassfish, delete andd again glassfish in Eclipse. </p>
  
  <p>I have Windows 7, but in another computer I have it too and I have worked happy. Then I decided to move project to my notebook, installing all stuff, and this happens. </p>
  
  <p>Any recommendation?</p>
