How to install an SSL Cerificate on Server 2008R2 Terminal Server

I have a Windows Server 2008 R2 running RDS/Terminal server and it is  functioning fine

-      The server is configured as a stand-alone workgroup server and not in a domain
-      We setup and configured RDS for 3 external users to only access a database application running on the server. That’s now working fine
-      Up till recently, users were typing in the public IP address linked to the server. We don’t want users to use the IP address
-      I created a new cname/alias sub domain called remotegf.domainname.com at the registrar (without giving you the exact domain and of the client)
-      I ordered and validated an SSL Certificate pointed to   remotegf.domainname.com  
-      After the validation, NS sent me the .CRT file to import. I placed the file on the server and just clicked on it and it successfully imported the certificate. It said it was successful. In the interim, we had to create a new free certificate on the server which allowed the external users to connect
-      However, when I checked the server, I don’t see the certificate

Am I doing something wrong?
All I want to do is replace the free built-in created certificate for the newly purchased SSL certificate


The server creates a .cer extension
the purchased certificate is a .crt extension
Any help would be appreciated
