title: IIS PowerShell Application Pool set as 'NetworkService' Account
body: <p>I'm trying to create an Application Pool in IIS7 using PowerShell. I want this to run under the NetworkService account but currently this appears to try and set itself as an 'Other' user on the Application Pool rather than being recognised as a built-in account. 
  My PS looks like this currently: 
  <code>Set-ItemProperty $iisAppPoolDir -name processModel -value @{userName="NetworkService";identitytype=3}</code> </p>
  
  <p>Now this usually should also have the <code>password="*****";</code> field available to allow me to create the application pool and have the user log in. I've left this out, hoping it would be identifiable, but it's not worked. </p>
  
  <p>Any help appreciated! </p>
