Java SE (Java Platform, Standard Edition)

Thanks in advance for your help, I am determined to find out why Java applets won't run in IE 7 but will run in FF on this one PC!

I have done all the complete Java uninstall/reinstall directions
I have turned off spyware checking, firewall, antivirus software

Frankly I doubt it is that, as FF runs fine.

When I run one of the test applets on the Internet, JRE comes up in the system tray, the Java logo appears in the applet box, then it says error. When I check the error console, it says:

java.lang.ClassNotFoundException: JavaVersionDisplayApplet.class

caused by:
java.net.SocketException: Permission denied: connect

Java is configured to use browser settings, IE automatically detects settings. It sure seems something is preventing the socket connect.

How can I find out what is causing this?
