title: What are the app pool identity and account for anonymous access for?
body: <p>I understand what the two are used for, <em>except</em> I don't know what each does--i.e. what one is for vs. what the other is for.  (I usually set them to the same account anyway.)</p>
  
  <p>If you're not sure what accounts I'm talking about, in the IIS manager thingy:</p>
  
  <ul>
  <li>Right-click on the app pool in question, go to Properties, and click the Identity tab to see the App Pool Identity.</li>
  <li>Right-click a Web site, go to Properties -> Directory Security, and click Edit under Anonymous Access and authentication control to view the Account for anonymous access.</li>
  </ul>
