Be sure that your browser, from which you started the CommDiag
applet, allows you to connect to local host. I had this problem
with IE.

You may try to run CommDiag from command line:
java -classpath interclient.jar
interbase.interclient.utils.CommDiag

This should work unless you have default security policy file in
the $JAVA_HOME/jre/lib/security folder.
