After cding to my folder I enter
python -m SimpleHTTPServer
and get
Serving HTTP on 0.0.0.0 port 8000 ...
<
Try browsing to http://localhost:8000/test.html or http://127.0.0.1:8000/test.html (those two should be exactly the same thing as long as your hosts file isn't all crazy-like).
0.0.0.0 is usually used by Windows as the "Not connected" IP, and can also be used as a sort of wildcard for when dealing with IPs. I am a bit confused at why your HTTP server is trying to host on 0.0.0.0, though. You may need to edit some config files and set that to 'localhost' or '127.0.0.1'.
