I googled [^]"HTTP Error 404 - File or directory not found". I got about 207,000 results.

First TWO being:
MSDN: How to resolve "HTTP Error 404"[^]
MSDN: How system administrators can troubleshoot an "HTTP 404 - File not found"[^]


Few more specific to 404.3 error:
MSDN Blog: The page you are requesting cannot be served because of the extension configuration[^]
HTTP Error 404.3 - Not Found The page [^]
The page you are requesting cannot be served because of the..[^]

For most of them, it occurs with service hosting that is resolved by:
1. Run Visual Studio Command Prompt as "Administrator".
2. Navigate to C:\Windows\Microsoft.NET\Framework\v4.0\Windows Communication Foundation.
3. Run this command servicemodelreg –i.
