Help for Internet Explorer errors
Microsoft Internet Explorer displays error information at the top of the window in the title bar, as well as within the window. The error that you see depends on several factors:
- Protocol: If IE can communicate with a web server, then errors may arise from the HyperText Transfer Protocol (HTTP) and are defined by a numeric status code and textual reason. Errors with the DNS or TCP protocols may prevent IE from communicating with a web server.
- Some servers (e.g. those using Microsoft IIS) extend HTTP status codes to more specifically define errors.
- Servers will also augment HTTP protocol errors with text that elaborates on the error, e.g. standard Apache error messages.
- Some sites will have further customized error messages, e.g. creative HTTP 404 errors
- Version: Error messages vary with the version of Internet Explorer being used. Messages below are for IE versions 8 (current) and 7. IEv6 has slightly different messages (as noted).
- Friendly messages: If the error message from the server is brief, then Internet Explorer will elaborate with a “friendly HTTP error message”. You may need to control whether Internet Explorer uses friendly error messages (e.g. turn them off) because they can sometimes obscure the cause of an error.
