This means that you have been blocked from accessing a site. This usually means that a valid logon ID and Password, and perhaps valid a IP Address are required for access.
This is probably the most common error an Internet user will receive. The code means that the web page does not exist at the location referenced. Usually you receive this error code when you are following links from other pages. Search Engines, such as HotBot, AltaVista, and Yahoo, are notorious for referring to expired pages. You can often find the page you are looking for by searching the site. To do this, you go to your browser's address box and delete the file name, i.e. with HTTP://www.anysite.com/reports/system/paper.html, you would erase the paper.html portion (HTTP://www.anysite.com/reports/system/) and resubmit. If you still receive a 404 error, then delete "system/", (HTTP://www.anysite.com/reports/), and submit. Continue until you reach a valid link. You can usually find the document on the site, but in a different location. If you cannot find the document and you really need it, you can contact the WebMaster for that site. There is usually a mail reference to this individual on the Home Page of a Web Site.
This response is similar to the 404: File Not Found error code discussed previously, and is unique to Microsoft Internet Explorer browsers.
This response may not mean there is an actual error. This code is unique to Netscape Browsers. What it really means is that some of the files being downloaded from that Web Site did not arrive in time. This often happens on complex sites, with many figures and files to download, to construct the page in the Netscape Browser. The recommendation is to attempt to access the site a second time or perhaps even a third. Place the cursor after the address and hit enter. If this problem persists after three tries, there is probably something wrong with the site.
This message usually means that you were trying to access an Secure Page and you are not an authorized user. However, it could also mean the site is temporarily busy, e.g. too many users accessing the site. The recommendation is that you attempt to access the site for a second time. If this fails, then you should wait a hour or two, and try again.
This error code usually means that the site you are looking for, no longer exists or that you have mistyped the address. DNS stands for Domain Name Server and is the foundation of the Internet. The Domain Name, such as LMMSSPECIALTY, is translated into an IP Address, such as 129.197.124.68, for access across the Internet or the LMMS Intranet. If you receive this error, you should first check the accuracy of the address you were attempting to access. On some Web Servers, the names are Case Sensitive, e.g. File is different than file. |
