Before proceeding with the steps outlined below, please ensure that you are indeed getting the RED X issue. The Red X issue is often confused with the (more likely) missing plugin icon which is easily remedied by downloading and installing Java.

RED X IMAGE SYMPTOMS:

An applet does not load, and the Java Plug-in Control Panel may show the following error:

java.net.UnknownHostException: www.xxxxx.com
at java.net.PlainSocketImpl.connect(Unknown Source)

Or, you see an image that looks like a small white box with a Red X in it

Or, the browser cannot display the program and displays the error message, "Loading Java Applet Failed..."

This issue is typically caused because Java could not obtain proxy information from your web browser. To learn more about this problem and its resolution, please visit: http://www.java.com/en/download/help/redximage.xml
