If you have published Remote Desktop Web Access out of the box, and you visit

As an added bonus, HTTP requests are redirected to HTTPS as well.

I also generally recommend to create at least the certificate public/private key pair always on the system that will in the end host the certificate. This reduces the risk of getting the private key compromised when you create key pairs on a different system and then have to…
