title: Visual studio unable to find the w3wp process
body: <p>I have an intermittent problem with visual studio unable to see the running W3wp.exe process when trying to attach to process, other instances of visual studio can see the process and restarting visual studio makes it appear in the attach to process list.</p>
  
  <p>hitting the refresh button makes no difference and I can use the web application while unable to see the process in the list.</p>
  
  <p>Any ideas?</p>
