Web hosting providers which are not supported
Their server returns "404 Not Found" responses when a script is first installed. Some users have reported success with spaceports.com, but in general there have been problems. Also spaceports.com FTP does not adhere to the FTP protocol through its lack of support for the PORT xfer method.
Their servers are not configured in a standard way. None of my scripts would run there without constant, expensive customization of the source code to meet their arbitrary undocumented configuration.
Windows NT 4.0 with non-Microsoft FTP
Any web server running Windows NT 4.0 with a non-Microsoft FTP server is not supported.
