Certificate Revocation Alert

[Guest]

Hi,

I'm hoping someone can help me here, I have a number of users, on a Windows
Server 2003 Terminal Server (with Citrix Presentation Server 4.5), who are
currently seeing the following pop-up message when they visit SSL secured
websites within the ICA sessions.

"Revocation information for the security certificate for this site is not
available. Do you want to proceed?"

I have trawled the net and have found a 2 common recommended fixes,

1) Remove the check from "Check for server certificate revocation" in
advanced options.
2) Manually specify a proxy server within the LAN settings.

The first fix is not applicable as that option is not checked anyway and the
second fix, manually specifying the proxy, is already in place as we push out
fixed proxy settings through a GPO.

However, with both of these fixes in place the users are still experiencing
the issue. It started on 15/10/07, to the best of my knowledge no new
software has been installed nor does the issue effect every user on the
terminal server.

I can resolve the issue by removing the proxy server settings, restarting IE
and then getting the users to connect back to the SSL sites which were
experiencing the problem, you can then put the proxy server back in and the
issue stays fixed.

Any thoughts on what might be causing this type of behavior and how I can
prevent it happening again would be greatly received. Even any thoughts on
how the certificate revocation works with IE would be great and how a proxy
server might cause the problem would be great.

Thanks in advance....

Hi:

I am having this problem also. I spent several hours online with norton
antivirus and they could not fix it for me. If anyone has any idea on how a
computer illiterate operator can remove this security alert it would be
greatly appreciated. Thank you
