title: *** ERROR: Symbol file could not be found. Defaulted to export symbols for ntkrnlmp.exe
body: <p>Hello Stackoverflow community,</p>
  
  <p>I am trying to debug an application on <strong>Windows 10</strong> and require windows debugger framework to load symbols to run certain commands in the (windows kernel debugger) kd.</p>
  
  <p>Each time I load the kernel debugger (kd) on the command prompt by typing kd -kl (NOTE: you would need to enable bcdedit -debug on for it to work), I get the below stack trace:</p>

  <li>At first glance, it appears that my sympath is not configured. </li>
  <li>I configure it to point to a path on my file system (see next point). </li>
  <li><p><code>.sympath srv*C:\symbols*https://msdl.microsoft.com/download/symbols</code></p></li>
  <li><p>Now, I set !sym noisy and do a .reload and I get the following trace</p>

   noisy mode - symbol prompts off

  <p>I also tried performing the steps explained in <a href="https://stackoverflow.com/questions/4828583/error-symbol-file-could-not-be-found-windbg-exe">ERROR: Symbol file could not be found. windbg.exe</a> and <a href="https://stackoverflow.com/questions/9044926/errorsymbol-file-not-found-in-windbg">Error:Symbol File not found in WinDbg</a> but no luck. I get errors that indicate several 404 errors.</p>
  
  <p>It always points to this file ntkrnlmp.exe and says its missing(or not found).</p>
  
  <p>Has anyone faced similar issues in the past? If so, what can I do to get this fixed? </p>
