Error message "Revocation information for the security certificate for this site is not available. Do you want to proceed? [Yes] [No] [View certificate]

I followed what you wrote and it worked!!  Thank you so much CyrilRandle!!  :)

This was very helpful thank you. This has been bothering me too for the last month. I don't know why it just started happening after using my laptop for 3 years.

But I went into the Tools option on the internet tools bar and did it that way. Advance button and then scrolled down to Untick the box ' Check for Publisher's Revocation'

This is a terrible suggestion, akin to stopping your smoke detector from going off by removing the battery. 

A Certificate is a document which establishes trust between the browser and the website you (or in the case of Java, an application) are visiting. Certificates work via a certification path.  You do not "trust" the issuer, but you trust someone who does.  A "CRL" is a "Certificate Revocation List", which is a list that is checked to determine if a given certificate is still "trusted".  If a certificate appears on a CRL, it means it has been revoked, i.e., the issuer no longer trusts it.  There are many reasons this can happen, for example, compromise of the password that is used to access the certificate, exposure of a certificate's private key, etc.  

When you recieve a certificate error, it means that although the certificate appears to be valid (the url matches that specified in the certificate, and the certificate expiry date is valid i.e., the certificate is not expired) BUT there was no valid CRL available to check the revocation status. 

This means that the certificate may be valid, or it may be revoked, but in either case your browser can't tell. 

In practical terms, consider the certificate for your banking insitution becomes compromised. The bank issues a certificate revocation, and places the cert on the CRL.  A bad guy creates a copy of your banking site, and uses the compromised cert to establish trust.  When the site is visited, the browser cannot find the CRL, so doesn't know the certificate is revoked.  It trusts the fake site, and you are not provided with any prompts or warnings. 

I don't know why Java is throwing CRL revocation errors...it's usually a problem with the browser reaching the CRL Distribution Point (for whatever reason). But turning off CRL checking is a bad idea. 

I didn't realize the problem could be with Java. I reset my security settings (turning CRL checking back ON) in IE 9. Thanks.

Thanks..it worked for me......
