We have an internal Microsoft Windows 2003 CA server running to handle certificates for our VPN users. The site was configured to require SSL to access the enrollment page and a certificate is installed on the server.
This was working fine but suddenly we are having a problem where the redirection is not working. If I enter https://servername/certsrv
I get a page cannot be displayed. If I enter http://servername/certsrv
I get a message that secure communications is required.
I've verified that the certificate is valid and don't see anything wrong with the configuration. There are no messages in the event or IIS logs.
Where else can I look to get this resolved?
