400 - Bad Request
Problem:
There's something wrong with the address you entered. You may not be authorized
to access the web page, or maybe it no longer exists.
Solution:
Check the address carefully, especially it the address is long. Make sure that
the slashes are correct (they should be forward slashes) and that all the names
are properly spelled. Web addresses are case sensitive, so check that the names
are capitalized in your entry as they are in the original reference to the
website.
401 - Unauthorized
Problem:
You can't get onto a website, because you're not on the guest list, your
password is invalid or you have entered your password incorrectly.
Solution:
If you think you have authorization, try typing your password again. Remember
that passwords are case sensitive.
403 - Forbidden
Problem:
Essentially the same as a 401.
Solution:
Try entering your password again or move on to another site.
404 - Not Found
Problem:
Either the web page no longer exists on the server or it is nowhere to be found.
Solution:
Check the address carefully and trying entering it again. You might also see if
the site has a search engine and if so, use it to hunt for the document. (It's
not uncommon for pages to change their addresses when a website is redesigned.)
To get to the home page of the site, delete everything after the domain name and
hit the Enter or Return key. For example: if the address is:
http://www.allsher.com/english/html/email.htm
remove:
english/html/email.htm
503 - Service unavailable
Problem: Your Internet service provider (ISP) or your company's Internet connection may be down. Solution: Take a stretch, wait a few minutes and try again. If you still have no luck, you may have to phone your ISP or system administrator.
550 - xxxxxxxxx is not a known user
Problem:
Using e-mail, you sent a note to an e-mail address that isn't recognized at the
mail server you've specified. The e-mail note got all the way to the mail server
(so that part's right), but you may have entered the user part of the e-mail
address incorrectly or the user may no longer have an account on that server
Solution:
Make sure you entered the correct e-mail user name. If you suspect it's an old
address or was mistyped in a note sent to you, try looking up a new address
using the person's name. Try e-mail address finding tools.
Bad file request
Problem:
Your web browser may not be able to decipher the online form you want to access.
There may also be a technical error in the form.
Solution:
Consider sending a message to the site's webmaster, providing any technical
information you can, such as the browser and version you use.
Cannot add form submission result to bookmark list
Problem:
You've just entered a search request and tried to save the result as a bookmark.
Though it may appear as a discrete address, the result isn't a legitimate URL,
so you can't add it to your bookmark list.
Solution:
Try saving the result page as an HTML page on your hard disk. Use the Save As
command then add the saved page to your bookmark list. Depending on the CGI
script behind the query, you may or may not be successful. But it's worth a try.
Connection refused by host
Problem:
You don't have permission to access the page or your password is incorrect.
Solution:
Try typing your password again if you think you should have access.
Error_117 ClearVideo Not Supported in Windows 3.1 or Unix Players.
Problem:
ClearVideo, a RealVideo compression/decompression (codec) library, is available
only for Windows 95, Windows NT, and Macintosh Power PC. Video clips created
using the ClearVideo codec cannot be played on Windows 3.1 or Unix.
Solition:
Need correct operating system Windows 95/98, Windows NT or 200 or Macintosh
Power PC.
Error_120 The logical drive chain is incompatible
Problem:
This error occurs under some operating systems when logical partitions are not
chained together in the expected order. DOS, OS/2, Windows 95 and Windows NT
require that logical partitions be chained together in ascending order. Some
other operating systems do not require this. For example, some versions of the
Linux FDISK utility chain logical partitions together in the order they are
created. This error message identifies a very dangerous situation; using the DOS
FDISK in this situation can cause loss of one or more partitions.
Solution:
To correct the problem you will need to backup the partitions and then delete
and recreate them and restore the data. You may need to use the same
partitioning program that you used to create the partitions in order to delete
them.
Error_500
Problem:
This server has encountered an internal error which prevents it >from
fulfilling your request. The most likely cause is a misconfiguration. Please ask
the administrator to look for messages in the server's error log.
Solution:
The web server provides this message whenever perl has a problem *of
any
nature*; i.e. syntax error, etc, anything. To debug the problem, you'll need to
locate the web server's error_log (try looking for /usr/local/htdocs and browse
around) and get the exact details from there.
Error_691
Problem:
Access denied because username and/or password is invalid on the domain
Solution:
Error 691 is caused by Dial-Up Networking (DUN) version conflicts created during
the installation of some programs or incorrect user name and password on Dial-Up
Network. Please note: CS2000 and
AOL5.0 do NOT use DUN. You must be
connected to the net by logging onto CS2000 or AOL5.0 then access Internet
Explorer.
Failed DNS lookup
Problem:
DNS stands for the Domain Name System, which is the system that looks up the
name of a website, finds a corresponding number (similar to a phone number),
then directs your request to the appropriate web server on the Internet. When
the lookup fails, the host server can't be located.
Solution:
Try hitting the Reload or Refresh button on your browser toolbar. If this
doesn't work, check the address and enter it again. If all else fails, try again
later.
File contains no data
Problem:
The site has no web pages on it.
Solution:
Check the address and enter it again. If you get the same error message, try
again later.
Helper application not found
Problem:
You're trying to load a file of a type that your browser doesn't recognize. Most
browsers can be enabled to view or load file types that they don't otherwise
recognize. These files can be sound files, movie clips, graphics, ZIP archive
files, or any other type of file you are trying to download.
Solution:
The dialog box that carries this message will tell you the file type that is
missing. You can then follow your browser's instructions for assigning a viewer
for each file format you wish to view online. It's often better to have certain
file formats not assigned to helper applications for Internet browsers. When
files are not assigned to helper applications, the dialog box you receive has a
"Save to Disk" option. This can often be useful when you want to
download files, such as ZIP archive files, to save them instead of extracting
them right away
Host unavailable
Problem:
The web server is down.
Solution:
Try hitting the Reload or Refresh button. If this doesn't, try again later.
Host unknown
Problem:
The web server is down, the site may have moved or you've been disconnected from
the Net.
Solution:
Try hitting the Reload or Refresh button and check to see that you are still
online. If this fails, try using a search engine to find the site. It may have a
new address.
Installation "Error 117"
Problem:
A certain batch of CDs contained a strange glue-like substance on them that
causes this error to popup because a track on the CD cannot be read.
Solution:
Clean the CD using Windex or some equivalent cleaner to remove the offending
substance. The other possible cause
of this error is a damaged or scratched CD, if cleaning the CD does not make the
error cease then the customer should order a replacement CD.
Network connection refused by the server
Problem:
The web server is busy.
Solution:
Try again in a while.
NNTP server error
Problem:
You're trying to log on to a Usenet newsgroup, but you can't get to it. The
Usenet server is something that's made available by your Internet service
provider, so it may be that this newsgroup isn't available at all.
Solution:
Make sure you've typed the URL correctly. If that doesn't help, try again later.
If the problem persists, contact your access provider and give them a piece of
your mind.
Permission denied
Problem:
You're trying to upload a file to an ftp site, and the site's administrator
doesn't want you to. Alternatively, you're using the wrong syntax when trying to
get a file. Or maybe the site is currently too busy to handle your upload.
Solution:
First check that you used the correct syntax. Then try again later. If the
problem persists, send email to the Webmaster and ask how you can upload a file
to that site.
Too many connections--try again later
Problem:
This is another variation on the rush-hour error message. You've picked the
wrong time to call, that's all.
Solution:
Do as it says--try again later, or keep hitting the Refresh button until you
succeed.
Too many users
Problem:
No ftp site has unlimited access: physical connections or administrator policy
allocate a number of anonymous users to a given site. When that number is
exceeded, all who try to log on receive this message.
Solution:
Just keep trying until you get lucky. However, on a busy site (like Netscape's
the week after a big announcement) or one with very limited access rights, you
may be out of luck. If so, check to see whether the site has mirrors, and try
one of those.
Unable to locate host
Problem:
The web server is down or you've been disconnected from the Net.
Solution:
Try hitting the Reload or Refresh button and check to see that you are still
online.
Unable to locate server
Problem:
The web server is out-of-business or you may have entered the address
incorrectly.
Solution:
Check the address and try typing it in again.
Viewer not found
Problem:
Your browser doesn't recognize a file at the Web or Net site you're visiting.
Viewable files aren't necessarily graphics--they can be sound files, movie
clips, ZIP or SIT archive files, and so on. If it's not a GIF or JPEG file, your
browser may not know what it is.
Solution:
The dialog box that carries this message will usually give a clue about the file
type that's missing. (You may see some gibberish about octet streams, but after
that you'll probably see some reference to graphic-TIFF, which gives it away.)
Look at CNET's Survival Kits for your computing platform (Mac, PC, or Unix) for
viewers for the most common file types. Then follow your browser's instructions
for assigning a viewer for each file format you wish to view online.
You can't log on as an anonymous user
Problem:
This message covers a multitude of sins. Some ftp sites allow people who aren't
members, some don't. Others may allow nonmembers, but limit the number of
visitors. Another possibility is that your browser doesn't support anonymous ftp
access. The way most browsers handle this is to submit "anonymous" as
the user ID and your email address as the password. The America Online browser
is one of the few that don't do this.
Solution:
Either try again later after the rush hour or enter your user ID and password
manually (using ftp software such as WS-FTP). Remember: your ID is anonymous and
your password is your email address.
