title: Site does not access and IIS has AppPool started, but needs to stop and start again
body: <p>I have a problem with my IIS. Each customer has their AppPool, but in some situations that I can't find out, some sites are unable to access. And when accessing the ISS, the AppPool has the status running (started) and only works again, when I click stop and then start.</p>
  <p>Has anyone had this problem and/or can help me with this, even to get more log about this possible error.</p>
