Remote Desktop still using old Cert


I have updated my Remote Desktop Sever with a new self signed certificate but when the client tries to run the app it still errors due to the old certificate.  

How do I get the system to use the new certificate?  

Do I have to delete the old one?  

Do I have to install the certificate on the VM server that runs the app?

Thanks for trying to help.

The answer to my questions were:

To get the new cert to be used I had to install it in IIS Manager and remove the old expired one.

No you don't have to install the cert on the VM that runs the app.

Here are the links I found most helpful in purchasing a new wild card cert and installing it on my Remote Desktop Services server and Active Directory server.
