I have just renewed our 3rd party SSL certificate issued by RapidSSL for a previously working RDweb set up.
I have installed the new certificate in IIS on our RD server, setting the binding on the Default Web Site to use it.
Also updated the services (RD Connection Broker Enable Single Sign On, RD Connection Broker publishing, RD Web Access, RD Gateway) in Server Manager - RDS - Deployment Properties - Certificates to use the new certificate.
When I browse to our RDweb URL I am able to log in and am shown a list of available apps. (The certificate being used for the site is confirmed as the new one) However, when I try to launch one of the apps I get the below error:
The thumbprint in the error is for the new certificate.
Further testing seems to prove the error only occurs when using a browser that has been used to access RDweb before (with the old certificate).
A browser on the same PC that has not accessed RD web previously allows the apps to open without the error.
Seems the client is caching the certificate somewhere an is not being updated with the new one.
How advice on what to check to fix this?
Cheers
