Firewall and Proxy Settings

Firewalls and proxy servers are the most common cause of IQ Chart connection problems. For software firewalls such as Norton, McAfee, or Windows XP, configure these applications to permit process javaw.exe (Windows Operating Systems) or Java (other operating systems) access to the Internet. Javaw.exe or Java is Sun Microsystems's implemenation of the Java programming language and run-time environment, the process IQ Chart runs under. Your firewall software vendor provides you with an icon that will take you to their firewall configuration panel to make the update.

Other kinds of firewalls and proxies also exist, usually in an office or school setting. If you are connecting to the Internet from your home, it is also possible that your ISP (Internet Service Provider) uses a firewall or proxy. IQ Chart can be easily configured to get through these firewalls and proxies. If you are connecting to the Internet through work or school, a firewall or proxy is almost certainly the cause of your connection problem. In any of these cases, here's what to try:

Click the Setup button on the login window of IQ Chart.
Type in the proxy host name and port number. If you are not sure about this, you can either ask your system administrator or go to your web browser and check out the proxy settings.
If you need to type in a proxy username and password to connect to the proxy server, check the Proxy requires username and password checkbox. Input your proxy username and password. Make sure that you do not type in IQ Chart's username and password.
Close this window and try signing into IQ Chart again.

One way to determine what the correct proxy settings are is to check the settings on your web browser:

Netscape Navigator/Communicator

Pull down the Edit menu, then click on Preferences.
A new window called Preferences will appear.
Select Advanced, then select Proxies.
If manual proxy configuration is checked, click on the view button to see your proxy information. Be sure not to change any of it!
Write down all of the proxy information before clicking on the Cancel button.
Go back to the Setup in IQ Chart and type in the proxy information.

Microsoft Internet Explorer

Pull down the Tools menu, then click on Internet Options.
A new window titled Internet Options will appear.
Click on the Connections tab, then select either the Settings button for your dial-up connection or the LAN Settings button for your broadband connection. Broadband connections are typically cable or DSL Internet connections.
Find the section called Proxy server.
If there is a check in the box next to Access the Internet using a proxy server, write down the address and port number of your proxy server, then click on the Cancel button.
Go back to the Setup in IQ Chart and type in the proxy information. Find the IQ Chart Setup button at the IQ Chart login screen.

If you try this or it doesn't apply to your configuration and you still cannot log into IQ Chart, contact your network administrator to make sure that your firewall and proxy settings are correct. If you are connecting to the Internet from your home, call your ISP to find out if they use a firewall or proxy server.
