I have installed UAG 2010 sp2, configured a https trunk, and published RDS via the trunk. The portal is available for external users to login using Active Directory. Once they login, they can see an icon for their published Remote Desktop (predefined). However, upon clicking the icon, they are presented with a security message:
"a website is trying to start a remote connection. make sure that you trust the publisher before you connect. The remote computer could harm your local or remote computer. Make sure that you trust the publisher before you connect.
I have installed publicly resolvable hostname certificates for the portal name and the RDS connection broker.
Has anyone been able to successfully remove this message?
