IE claims valid certificate is revoked

[newsgroups]

When users visit one of my company's sites, they receive a "The
security certificate for this site has been revoked" security alert
after they log in. However, our SSL certs have not expired nor have
they been revoked. This only happens when the user's "advanced"
settings (in Internet Tools) has the "check for server certificate
revocation" option checked.

Does anyone know what is causing this? One of the sites this error
happens on is http://www.ouranthemaz[REMOVE_THIS].net (get rid of the
[REMOVE_THIS] part, obviously).

You probably won't get the error message because it doesn't come up
until after a user has logged in.

If it matters, we are running IIS 6.


Any help is appreciated.

This can happen if the certificate revocation list retrieval takes too long.
That can happen frequently, so that's why I have that particular Advanced
Internet Options box unchecked. This has been a long-standing issue.

I'm wondering if this is the problem in your case:

If no joy, I would contact the issuer of the certificate for possible help:
