    Hi,

    I just installed the IIS web server role from server manager and copy an .aspx to wwwroot. But when I start the website and access the localhost. It just return 404. I think the URL should be correct.How could I access the aspx from local IIS server?

    Thanks in advance.

    Hi Jamsyan998，

    You may first check the HTTP status code in the IIS log. IIS returns a numeric code that indicates the status of the response.

    IIS 7.0, IIS 7.5, and IIS 8.0 define the following HTTP status codes that indicate a more specific cause of a 404 error:

    404.0 - Not found.
    404.1 - Site Not Found.
    404.2 - ISAPI or CGI restriction.
    404.3 - MIME type restriction.
    404.4 - No handler configured.
    404.5 - Denied by request filtering configuration.
    404.6 - Verb denied.
    404.7 - File extension denied.
    404.8 - Hidden namespace.
    404.9 - File attribute hidden.
    404.10 - Request header too long.
    404.11 - Request contains double escape sequence.
    404.12 - Request contains high-bit characters.
    404.13 - Content length too large.
    404.14 - Request URL too long.
    404.15 - Query string too long.
    404.16 - DAV request sent to the static file handler.
    404.17 - Dynamic content mapped to the static file handler via a wildcard MIME mapping.
    404.18 - Querystring sequence denied.
    404.19 - Denied by filtering rule.
    404.20 - Too Many URL Segments
