title: Getting Access is denied for the user NT AUTHORITY\NETWORK SERVICE.while accessing coreservice Tridion
body: <p>When I was writing the custom page using tridion 2011 core services from my local, I used my tridion credential to access the core services webservice.</p>
  
  <p>Now when everything is done on my local :), I published my website and simply did below things on the Tridion CM server.</p>
  
  <ul>
  <li>In the IIS I created new aplication website with name "CoreServices"</li>
  <li>Used the application pool using Network USer</li>
  <li>Copied my published website in the coreservice mapped folder.</li>
  <li>Removed my credential from web config and implemented logic to read the user details who is accessing the website/custom page</li>
  <li><p>Now when I am trying to access the coreservice website, I am getting below error</p>
