Runtime Error

400 Bad File Request

Usually means the syntax used in the url is incorrect (e.g. uppercase letter should be lowercase letter; wrong punctuation marks)

401 Unauthorised 

The website server is looking for some encryption key(s) from the client (your computer) and is not getting it. Also, a wrong password may have been entered. Try it again, paying close attention to case sensitivity..

403 Forbidden/Access Denied 

Similar to 401, special permission is needed to access the website A password and/or username may not be correctly registered on the websites database. Other times the website server may not have the proper permissions set up on its directories...

404 File Not Found

Server cannot find the file you requested. Refreshing the page (F5) should resolve this problem, although continued error messages may mean the page is no longer available, that there is considerable internet congestion (in which case the user should try again later).

Alternatively the file could have been either been moved or deleted, or you entered the wrong URL or document name. Look at the URL. If a word looks misspelled, correct it and try it again. If that doesn't work backtrack by deleting information between each backslash, until you come to a page on that site that isn't a 404.

From there you may be able to find the page you're looking for. This has to be the most common Internet Explorer Error message on the Internet!

408 Request Timeout 

Client (your computer) stopped the request before the server finished retrieving it. A user will either hit the stop button, close the browser, or click on a link before the page loads. Usually occurs when servers are slow or file sizes are large.

500 Internal Error

Couldn't retrieve the HTML document because of server-configuration problems.

Contact website administrator...

501 Not Implemented

Web server doesn't support a requested feature.

502 Service Temporarily Overloaded 

Server congestion; too many connections; high traffic. Keep trying until the page loads. This can be a common occurrence at peak news times eg. the Twin Towers during September 2001 brought CNN and the BBC news sites to a slow crawl and many folks got this error.

503 Service Unavailable 

Server busy, site may have moved, or you lost your dial-up Internet connection!

Bad File Request 

Browser may not support the form or other coding you're trying to access.

Connection Refused by Host 

Either you do not have permission to access the site or your password is incorrect. Try again!

Errors on Page

This error message is a catch-all statement meaning there is something on the web page that the browser either hasn't read properly (connectivity problem) or there are missing items in the web page itself. This problem normally affects the graphics on a web page.

This can be a temporary glitch (caused by insufficient bandwidth), and may be quickly resolved, or it can have a more complex and longer term problem. With regard to most cases of this Internet Explorer Error message, it is due to not having given sufficient time to download the page you are requesting.

It is necessary to wait until the bottom left hand corner of the page reads 'done' before selecting any other links on the page to move forward.
