Browser Errors

Why do I get the error 404 Not Found?

The browser could not find the specific document that you requested on the host computer. To resolve this error, check the Uniform Resource Locator (URL) syntax (some URLs are case sensitive). In addition, the page may have been removed, had its name changed, or have been moved to a new location.

Why do I get the error 403 Forbidden/Access Denied?

The Web site you requested requires special access permission (for example a password).

Why do I get the error 503 Service Unavailable?

The host computer is too busy. Try viewing the page again after about 30 seconds.

Why do I get the error Bad File Request?

The form or the Hypertext Markup Language (HTML) code for an online form has an error.

Why do I get the error Cannot Add Form Submission Result to Bookmark List?

The results of a form (such as a WebCrawler search) cannot be saved as a bookmark. A bookmark can only be a document or an address.

Why do I get the error Connection Refused by Host?

This is a version of the 403 error. The Web site you requested requires special access permission.

Why do I get the error Failed DNS Lookup?

The Web site's URL could not be translated into a valid Internet protocol (IP) address. This error is common on commercial sites because the computers responsible for translating the IP addresses are overloaded. Try again later when there may be less Internet traffic. This can also be caused by a URL syntax error (the URL has incorrect format).

Why do I get the error HTTP Server at Compressed <xxx>.com:8080 Replies:HTTP/1.0 500 Error from Proxy:?

This error is common with proxy servers (a server on a local area network that lets you connect to the Internet without using a modem). The proxy is either down, busy, or cannot interpret the command that was sent to it. You may want to wait for 30 seconds or more then try viewing the page again. If the problem persists, contact the network administrator of that proxy. Whatever is shown instead of <xxx>.com is usually your Internet service provider.

Why do I get the error File Contains no Data?

The browser found the site, but nothing in the specific file. Try adding ":80" (without the quotation marks) to the URL just before the first slash, for example: http://www.ntws.net:80/

Why do I get the error Helper Application not Found?

You have attempted to download a file that needs a helper program, and your browser cannot find the program. On the browser's preferences or options menu, make sure the correct directory and file name are entered for the helper program. If you do not have a helper program, save the file to disk and obtain the helper program.

Why do I get the error NTTP Server Error?

The browser could not find the Usenet newsgroup that you tried to access. Make sure the news server address is correctly listed in your browser's preferences or options menu and try again.

Why do I get the error Not Found?

The link no longer exists.

Why do I get the error Site Unavailable?

Too many users are trying to access the site, the site is down for maintenance, there is noise on the line, or the site no longer exists. This can also be caused by a user URL syntax error.

Why do I get the error TCP Error Encountered While Sending Request to Server?

This error is caused by erroneous data on the line between you and the requested site. This may be hardware related. Report the error to your network administrator and try again later.

Why do I get the error Too Many Users?

The site is busy. You may want to try again after about 30 seconds.

Why do I get the error Unable to Locate Host?

The URL did not return anything, the site is unavailable, or the Internet connection was dropped. Check the hardware connections and URL syntax.

Why do I get the error Cannot Connect to Server?

This error can occur if you are using Secure Sockets Layer (SSL) security ("https" at the beginning of the URL) when you are connecting to certain Web servers. This behavior has been seen on C2's StrongArm servers with Internet Explorer 3.x and 4.0 in Windows 95 and Windows NT.

FTP Errors

Because there are many FTP programs available, error messages may vary.

Why do I get the error Invalid Host or Unable to Resolve?
This is the FTP equivalent of the Web browser's 404 error. The FTP program cannot find the site requested. This can also be caused by a URL syntax error.

Your FTP program connects then suddenly stops responding.
NOTE: this is not an error message. If this occurs shortly after you log on, try using a dash (-) as the first character of your password. This turns off the site's informational messages, which may be causing a conflict with the FTP program.

Why do I get the error Too many consecutive transmit errors?
NOTE: this is not an error message. This indicates that line noise has prevented the FTP program from continuing. This could be a hardware problem, the command string sent to your modem may be incorrect, or the modem may not be properly configured.

Usenet Errors

Usenet is the collection of computers and networks that share news articles. It overlaps with the Internet, but not identical to it
These type of errors are usually specific to your news reader.

Invalid Newsgroup

This is caused by a URL syntax error, or the news server may not carry the newsgroup you are trying to access. See your network administrator for assistance.

No Such Message

This message indicates an outdated message. The message you requested is still in the index, but has been removed from the server.

Could Not Connect to Server

The news server is busy or is down, or you do not have access to the news server. Another possibility is that your browser or news reader program has been set up incorrectly.

The Message Appears Unintelligible

NOTE: this is not an error message. This is caused by a binary (non-text) file, such as a picture, movie, or program, that has been encoded into text characters. Most news readers include automatic decoding of binary files. To decode a file, use a decoding program or purchase a news reader that supports automatic decoding.

E-Mail Errors
Most mail errors are URL syntax errors. Commas and spaces are not allowed in e-mail addresses.

Why do I get the message Unknown User?

This may be caused by a URL syntax error. The name was typed incorrectly or the address was typed incorrectly.

Mail for a mail list stops appearing

How Do I........

FTP - Uploading/Downloading your web pages.
Once you have "built" your home pages you are ready to send them out to the Internet. This is really quite simple if you carefully follow these instructions.

1. Open your FTP (File Transfer Protocol) software.

2. In the "Host Name" box type in ftp.ntws.net.

3. The "Host Type" box should say Unix (standard).

4. In the "User ID" box type in your user name. Remember to use lower case.

5. In the "Password" box type in your password. Remember to use lower case.

6. In the "Local PC" box type in the directory in your computer you want to access.

You will now be logged into your directory on the Internet. In the "remote system" Section FTP, you will see a "public_html" directory.

Double click on the "public_html". This will put you in the part of your directory where you will deposit your web pages. Notice you can make additional directories for better organization of your files by clicking on "Mkdir" in the "remote system" side of FTP.

When you are ready to send out your pages, highlight the files you want to send and click "send", this will deliver your files to your directory. You will need to change all your html extensions to "htm" extensions once you send them from your computer. NOTE: You will need to name your home page "defaul.htm". When someone types in your URL it will default to "default.htm" which is your main page.

When you want to update your pages simple login in as above, highlight the file you want to change and click "receive". This will download that page to your computer for editing.

To access your page through your browser, type in

"http://www.ntws.net/your_user_name/default.htm".

If links on your pages are not working, most likely the link(s) are pointing to the wrong page. Carefully go back through your HTML and double check all HTML and directories.

Remember, in-house Technical Support is not provided for development of Home Pages.
