I've enabled RPC over HTTP on a new Exchange 2007 installed into an SBS2003 domain on a new server 2008 box. I have created a SAN certificate and have added the Autodiscover entry to DNS. I have also exported and installed the ROOT certificate to a PC but cannot connect via RPC over HTTP. I have checked the URL's etc and these seem fine.
I have ran the Exchange connectivity tool and i get the following:
Testing SSL Certificate for validity.
The SSL Certificate failed one or more certificate validation checks.
Validating certificate name
Successfully validated the certificate name
Found hostname OWA.CSCIENCES.CO.UK in Certificate Subject Common name
Validating certificate trust
Certificate trust validation failed
Certificate chain could not be built. You may be missing required intermediate certificates.
I installed the certificate from the Exchange 2007 server but do i need anything from the SBS2003 (DC) box as well ?
