I recently migrated a client to exchange 2012. I purchased a certificate and installed it. External access to the server is fine, no cert errors. The problem is that "server.myclient.local" is how the server resolves internally and that name does FQDN does not match that of the certificate. Do I need to rekey the certificate to include the internal FQDN as well? What are the steps to do that? Any help is appreciated.
