This is basically an Internet Explorer 7 Websites Security Certificate problem! You have to self-sign the certificate on the client computer or add the URL manually to the trusted security zone.
When you are trying to access a secure web page, you receive the warning message:
“There is a problem with this website’s security certificate. The security certificate presented by this website was not issued by a trusted certificate authority.”
“Security certificate problems may indicate an attempt to fool you or intercept data you send to the server.”
