  </code></pre>
  
  <p>No errors while strtup.</p>
  
  <p>I found in the Internet, that the solution is to set <code>HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableUserTOSSetting=0</code> and reboot a machine.</p>
  
  <p>But I can't reboot a machine since it is in use.</p>
  
  <p>What is the nature of this error?</p>
  
  <p>Is there any way to install <code>red5</code> on Windows Server without rebooting it?</p>
  
  <p>May be downgrade Java or red5?</p>
