First,
complete the WebCT Browser Tune Up (Note: UWG
uses WebCT v.3.8 Campus Edition (CE)...
and make sure you have applied these settings or you will encounter
problems while working with WebCT. Ensure your browser settings are
correct before carrying out any further troubleshooting or requesting
support for a WebCT problem.
Both
students and staff have lately been affected by the onslaught of a new
breed of noxious Internet nasties known as "parasites" that infect web
browsers, especially Internet Explorer. "Parasite" is
a shorthand term for "unsolicited commercial software" -- that is, a
program that gets installed on your computer which you never asked for,
and which does something you probably don't want it to, for someone
else's profit. For more information and to detect for parasites on your
computer as well as instructions on how to remove them, visit http://www.doxdesk.com/parasite.
Note that the detection will ONLY work on Internet
Explorer 5 (or later).
As well,
a number of innocuous programs designed to improve your web experience
can in fact degrade your use of WebCT dramatically, as can some system
software or web browser upgrades, patches and security fixes. Often
these programs will install after you choose "Yes" to a basic question
asking you if you would like to improve your internet experience. As
always, if you are in doubt about the need for a specific program it is
usually wiser not to install it.
The
following tips regarding 403 errors, Download Managers, Spyware, Adware
and Pop-up Stoppers will aid you in avoiding potential problems or
fixing them after they have occurred....
Top
a. 403 or Access Forbidden Errors
A
recent Internet Explorer 6 update/patch installed by Windows Update may
cause access problems for some users.
Symptom:
Access
is "Forbidden" and/or the error "403" is displayed when attempting to
log in.
Solution:
In
Internet Explorer 6 in the "Tools" menu select "Internet Options"
followed by the "Advanced" tab, deselect (uncheck) "Show friendly HTTP
error messages" which is under the "Browsing" section.

b.
Cannot login or computer tries to download a file
If you
have a download manager installed and are experiencing WebCT access
problems you may need to remove the download manager from your
computer. Download managers can adversely affect access to course
content and WebCT. In particular they can prevent logging in and also
the viewing of some content.
Symptom:
When I
try to log into myWebCT, my computer tries to download a file. E.g.
after entering the User name and Password, the PC prompts to save a
file. Alternative symptoms include complete inability to get past the
login screen.
Diagnosis:
The
problem is caused by Download Manager software that may be installed on
your computer system. At some point Real Download (a product of Real
Player) or Smart Download (a product of Netscape) was installed on your
PC.
Solution for Windows users:
1)
Click on the Start button.
2) Go
to Settings and open Control Panel.
3)
Double click on the Add/Remove Programs icon.
4)
Click on the installed download manager, either Smart Download or
Real Download to select. If you have both of these
programs, you will need to remove them both.
5)
After selecting the download manager, click the option to Change
or Remove the program.
6) You
will be prompted through the uninstallation of the program.
7)
After uninstallation, reboot the PC.
These
two download managers may be reinstalled the next time you visit the
Real Player or Netscape web sites and download files.

c. Some windows do not open correctly
Software
designed to eliminate “pop-up” windows opening while web browsing may
interfere with the functioning of WebCT. There are a range of names
these programs go by including Pop-Up Stopper, Defender and Zapper.
Pop-up stoppers may also be included with virus checkers and other
internet security software. See a more complete list of anti-popup ware
here: http://distance.westga.edu/webct/popuplist.html
Also,
see this Pop-up Help Guide
(http://academics.georgiasouthern.edu/dlc/webct/popup.php)
Note:
Some versions of Internet Explorer and Netscape 7.1 come with
a pop-up stopper automatically installed and turned on. See browser
tool options to disable the device or set it to allow
http://webct.westga.edu.
Also, see this Pop-up Help Guide
(http://academics.georgiasouthern.edu/dlc/webct/popup.php)
Symptom:
Inability
to view Discussion postings, Quiz pop-up windows, download links or
other tools that may be attempting to open in a new window.
Diagnosis:
Windows
Users: Either remove or disable pop-up software. It may be
possible to locate this software under Add/Remove Programs in the
Control Panel. See instructions as per Download Managers.
For
Norton Internet Security Users: Add UWG's WebCT IP address as
a trusted site so that the pop-ups will continue to work in WebCT.
1)
Open Norton Internet Security.
2)
Click on Norton Firewall.
3) Go
to Home Networking.
4)
Add 160.10.4.51 to add UWG's WebCT server to the list of trusted sites.
ZoneAlarm Firewall Users:
Here are some quick instructions on how to configure Zone Alarm with
WebCT. If you use a different firewall, you will find the same settings
on your version: http://distance.westga.edu/webct/firewalls.html.
Note that even if you disable the "anti-popup feature
you STILL may have to disable the "anti-javascipt feature".
Anti-PopUp Software: You
may need to "disable", "exit", "quit" or "shutdown" any pop-up stopper,
ad-ware prevention, or firewall software that runs on your computer, in
order to use certain WebCT tools. Recent releases of anti-virus come
with built-in anti-popup features.
Earthlink Users: Earthlink
now comes with a built-in anti pop-up ware automatically turned on --
you need to turn it off - see
this webpage for help turning the Earthlink pop-op blocker off --
if you need help, see the Earthlink
support website or call them at 1-800-719-4660.
PopUp Stopper (Panicware):
Used by Internet Explorer. Go here to find out how to locate and
disable PopUp Stopper (Panicware):

Blockers (Georgia Southern): Pop-up
help
http://academics.georgiasouthern.edu/dlc/webct/popup.php
Anti-Virus Software:
Recent releases of anti-virus software may interfere with your use of
WebCT. For example, Norton's Anti-Virus Software now comes with
built-in anti-popup, firewall, and anti-java-script features. If you do
not take care to disable or specify your WebCT sites as "ok" or set
your security at the "lowest" possible setting, you may not be able to
access http://webct.westga.edu at all (you may get an error or a "frame
mis-match error"). Also, you may not be able to use certain WebCT tools.

d.
Access Forbidden error or "Internet Optimizer" site loads when logging
in
The
helpdesk recommends all users install preventative measures against
spyware, adware, parasites and virii. An infestation of any of these
malicious programs can cause problems accessing WebCT or any web site.
A
common example of this type of malicious program is “Internet
Optimizer”. This program will redirect you to its own web site when you
attempt to log in to WebCT.
Symptom:
Upon
login user's browser is hijacked to the Internet Optimizer site and the
following (or similar) message appears:
HELP/NAVIGATION
ERROR - Forbidden
Access
to this URL is Forbidden
http://160.10.4.51/SCRIPT/CourseCode/scripts/serve_home.
To Prevent Infection:
Ad-aware
and SpyBot are simple to use tools for removing and preventing
infection of spyware, adware and parasites including Internet
Optimizer. Install at least one of these programs and run at least once
to remove any items that they uncover. Such software can be found on: http://www.download.com/
There
are inherent risks with installing any new software onto your computer.
Please check with your favorite expert for their recommendations before
proceeding.
Possible Solution for an Internet Optimizer
Infestation:
In
Windows go to the Start menu and select Settings.
Open the Control Panel and choose Add/Remove Programs.
Look
for Active Alert and Internet Optimizer. If these
entries are there, select Change Remove for each one in turn.
Follow the steps to remove the program.
It has
been known for these solutions to not completely remove the infestation
or for reinfection to occur. Reinstallation of the Browser or worse the
operating system is often the only cure. Alternatively install and use
a different brand of Web Browser. As the problem appears to be limited
to Microsoft products an alternative browser such as Netscape may be
the only solution.
SpyBot
and some virus checkers can be set to detect these nasties as they
enter your system. However you must ensure that you keep your virus
checker, spyware and adware checkers up to date to prevent reinfection
as the attackers regularly modify their programs to get around common
defences.
Important Note: Virus Checker
A virus
checker should be the first item installed even prior to
attempting a fix for any login problems.

e. Computer locks up or freezes when
trying to access links to certain files
Cause: If the link is to
a non-webpage type file.. for example, a link to a Microsoft Word
document, a PowerPoint file, or a .PDF file.. the problem could be that
your system is set to automatically open files of this type but your
computer cannot handle the particular file in this manner (either due
to file size or slow network connection)
You
might have a less frustrating time setting your computer to NOT
auto-open these types of files.. to instead prompt you to download them
(save them) to your computer and open off-line.
Directions
for PC/ Windows Operating System:
On
Desktop, Click on "My Computer"
Select C: drive
On the upper tool bar, select "Tools" and from pull-down menu select
"Folder Options"
Choose the "File Types" Tab
Select (Click to Highlight) type of file desired .. they are in
alphabetical order.. common types include .ZIP and .DOC files
... and then click on the "Advanced" button
Make sure the box "confirm open after download" is checked (if you want
your browser to prompt for manual download and open) or unchecked (if
you want your browser to try and automatically open files of this type).

f. Access problems persist
after above fixes applied
Cause: File sharing
programs
Peer-to-peer
software (for instance KaZaA, Napster, BearShare, Grokster or iMesh)
downloads spyware, adware and parasites on to your computer, hindering
or even preventing use of some software including WebCT. For example,
Note that KaZaA (but not KaZaa lite) automatically places the
PerfectNav parasite on your computer which causes a conflict with
WebCT.
Key
indicators that your system is infected with SpyWare
- Error messages referencing Perfect Nav or Internet
Optimizer
- Bombarded by pop-ups
- Slow or no network connection
- Computer freezing or hanging
- Frequent system crashes
- System slowdown
- Slow System Start-up
- Getting lots of SPAM emails lately?
Possible
ways to get rid of infestation:
1. Ad-aware
and SpyBot are simple to use tools for removing and preventing
infection of spyware, adware and parasites. Install at least one of
these programs and run at least once to remove any items that they
uncover. Such software can be found on: http://www.download.com/
2.
Some software is available to clean up specific applications. For
instance, DietK is a free way to clean up
infestations cause by KaZaA: http://www.dietk.com/
3.
For more information and to detect for parasites on your computer as
well as instructions on how to remove them, visit
http://www.doxdesk.com/parasite.
Note that this detection will ONLY work on Internet Explorer 5 (or
later).
4.
Specifically, to remove Perfect Nav: http://www.kephyr.com/spywarescanner/library/perfectnav/index.phtml
If the
problem persists after trying these measures you may need to
uninstall any peer-to-peer file sharing software.
Another
alternative is to download Mozilla Firefox 1.5 (www.mozilla.com/firefox/) and
use it as your browser for WebCT. Once downloaded and
installed, do not forget to disable the pop-up blocker or set it to
allow for http://webct.westga.edu.
*Note: Netscape 8 is not a supported browser for WebCT.
A note for Mac Users
Although
we rarely see these issues on Macintosh computers, as the browser is
the target, Mac users can also be infected. We recommend Macintosh
users also remain vigilant and install a virus checker where it is
available. A virus checker as always is an absolute necessity
regardless of computer platform.
