I am posting this to both R5/R6. Verisign's International Server CA- Class 3 expired for some of us on 01/07/2004.
We had to follow these instructions listed here at this url:
http://www.verisign.com/support/site/caReplacement.html
You will need to know the password to the keyfile.kyr to be able to replace the Intermediate CA certificate.
You can email me directly at sidbagali@yahoo.com if you need more or detailed assistance
Also if your java+ssl programs do not work... check this article out:
