I think Brad Mettee nailed it with his response.


And in this particular case, the certificate is for and, and the browser is complaining because it's being used on

Their certificate should have been issued for * instead of 
just the main site name. Unfortunately I think all of the certificate 
issuers charge big $$$ for that type of cert......


I have seen this sort of thing several times before with different
sites. The older versions of Firefox never picked up on it as often as
IE would. I just tried this site using IE and immediately received the
error message. The message stating: "The security certificate presented
by this website was issued for a different website's address. Security
certificate problems may indicate an attempt to fool you or intercept
any data you send to the server." It then went on to give me the normal
options of leaving the site or ignoring the error. Interestingly
enough, Firefox, on the same machine, does not provide any indication
that the certificate is questionable.

Given the choice of being warned about a questionable certificate or
having the browser silently ignore it, I would choose to be warned
about it.
