title: multiple users accessing wcf, stalls service
body: <p>we currently have this setup:</p>
  
  <p>1) a web site that fronts functionality to user, one of its modules connect to a separate web service (WCF) as reference.</p>
  
  <p>2) an internal web service only visible within the network that provides a separate functionality to the public website. it render and return some data and rdlc reports as byte array.</p>
  
  <p>When I tried running the web service's application pool under Network System, the website failed to access it. But when I set the web service to Local System it works. </p>
  
  <p>The only issue left is that whenever more users try to access this web service from the website, somehow, the web service stalls and a pool refresh is required to make it running again. I've checked the settings of the IIS for the web service and connections are set to unlimited.</p>
  
  <p>Help!</p>
