title: IIS7 Permissions Overview - ApplicationPoolIdentity
body: <p>We have recently upgraded to IIS7 as a core web server and I need an overview in terms of the permissions. Previously, when needing to write to the file system I would have give the AppPool user (Network Service) access to the directory or file.</p>
  <p>In IIS7 I see, as default, the AppPool user is set to <code>ApplicationPoolIdentity</code>. So when I check the task-manager, I see that a user account called <code>WebSite.example</code> is running the IIS Process ('<code>Website.example</code>' being the name of the website in IIS)</p>
  <p>However this user account doesn't exist if I try to use that to give permissions. So, how do I determine which user to give the permissions too?</p>
  <p>See below for the problem in screen shot. Our website (<a href="http://www.silverchip.co.uk" rel="nofollow noreferrer">www.silverchip.co.uk</a>) runs on the username SilverChip.co.uk. However when I add permissions, this user doesn't exist!</p>
