title: IIS doesn't start. Error code: C0000142
body: <p>My site worked perfectly fine.
  When I restarted IIS (for some scenarios check) - It stopped working, and gave me a page telling me to check the event viewer, there I get the following error:</p>
  
  <blockquote>
    <p>aspnet_wp.exe could not be started. The error code for the failure is C0000142. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account.</p>
  </blockquote>
  
  <p>This is NOT an ACL problem.</p>
  
  <p>Any ideas?</p>
