title: Can't start Apache on Windows Server 2008 R2
body: <p>I got the following error when trying to start apache:</p>
  
  <blockquote>
    <p>(OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions.  : make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down. Unable to open logs</p>
  </blockquote>
  
  <p>I could start it before. I guess after I enabled feature of windows '.NET Framework 3.5'. now I can't start it properly. I have checked the port:</p>
  
  <pre><code>netstat -aon|findstr "80"
   TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       4
   TCP    [::]:80                [::]:0                 LISTENING       4
  tasklist|findstr "4"
  System Idle Process              0 Services                   0         24 K
  System                           4 Services                   0        304 K
  </code></pre>
  
  <p>How to resolve this?</p>
