RDP Certificate issue

Having problems with RDP cert after changing Commercial cert to new email domain name
I just changed my email domain and have a Commercial cert for the new email domain that works fine in EX 2016, autodiscover, outlook, etc. I make RDP connections to the server hosting the Hyper-V EX 2016 server and it throws a server certificate error (name mismatch). I am not running TSS. I use the RDP connection to administer my remote server through CP Remote settings. How can I change the cert in the server to use the commercial cert for those connections?

Looks like you importerd the new cert to exchange with success but how does the host suppose to know it can be used for RDP?
Did you distribute the cert by GPO to member servers or did you add it manually to the local cert store?



Thanks you Patrick. Made sense once your comment was received.

You need to tell the RDS service which certificate to use.

This isn't an issue with distributing the certificate, as is already trusted.

Hopefully you are not directly exposing RDP to the internet.
