title: Debugging Tools for Windows: Symbol Proxy doesn't proxy
body: <p>I'm attempting to set up a symbol proxy using symproxy.dll from Debugging Tools for Windows. When I issue ".reload /f" from the debugger, none of the symbol files can be found. It looks like Symproxy isn't going out to the Microsoft Symbol Server to actually get the symbols. I see nothing in Wireshark, for example.</p>
  
  <p>SYMPROXY.DLL is definitely being loaded -- I can see some entries in the Event Log, and <a href="http://my-server/symbols/status" rel="nofollow noreferrer">http://my-server/symbols/status</a> returns valid-looking information.</p>
  
  <p>I've followed the instructions in the documentation as far as I can tell. Why won't symproxy go to Microsoft's site? What am I doing wrong? I need this to work, because the machine on which I'm debugging doesn't have external access.</p>
  
  <p>The box on which symproxy is running has Internet access -- I regularly use it for debugging. The symbol path configured in the registry for symproxy looks correct. It doesn't have to go through a proxy to get to the Internet, and I've configured that in the registry as well.</p>
  
  <p>When I use !sym noisy on the other box, it contacts symproxy, but simply says "file not found". It's like the symproxy is simply serving the content, rather than doing a lookaside to the MS symbol servers, like it's supposed to.</p>
