Hey Mike,

I've run into that as well. We got around it by going to internet options-> advanced-> and unchecking the 
"Check for server certificate revocation" option under security. I hope it helps.

Subject: Vista Certificate Revocation errors

I have a few Vista computers that, after login, are suddenly displaying 
the message "Revocation information for the security certificate for this 
site is not available. Do you want to proceed?". Answering Yes simply 
presents the Security Alert again. The only solution is to configure 
Internet Explorer not to perform this check. My certificate is from 
Verisign, valid, and I have crl.verisign.com added to my unauthenticated 
and temporary roles. So far I haven't seen this on XP, and so far it 
doesn't appear to be affecting all Vista users. It might have coincided 
with IE8 though.

I'm running CCA 4.1.6 with Agent 4.1.7. Any idea what might have triggered 
this error and what I can do about it? My Service Desk doesn't need 
another issue to deal with.

-Mike
