404.1 the file or directory was not found: The Web site cannot be accessed on the requested port.

Note that the 404.1 error will only appear on computers with multiple IP addresses. If a client request is received on a specific IP address/port combination and the IP address is not configured to listen on that particular port, IIS returns a 404.1 HTTP error. For example, if a computer has two IP addresses and only one of the IP addresses is configured to listen on port 80, any requests received from port 80 by another IP address will cause IIS to return 404.1 errors. This error should only be set at this service level because it is returned to the client only when multiple IP addresses are used on the server.
