I have been going around and around trying to get RPC Over HTTPS to work externally on SBS 2003. Everything seems to be configured properly including a RapidSSL certificate. I was looking at the Certification Authority on the SBS Server and I see that the Local Certifcation Authority is issued to domainCA whereas our certificate is issued to mail.domain.com. Could this be causing a problem and if so, could I remove the Certification Authority and reinstall it using mail.domain.com instead without messing anything else up? Thanks!
