The following message is received when user is trying to access the Remote Support Center Console.

The page requires a valid SSL client certificate. Your client certificate is untrusted or invalid. A Secure Sockets Layer (SSL) client certificate is used for identifying you as a valid user of the resource.

This is an environmental issue. IIS is rejecting the request from Internet Explorer Browser. 

IIS may need to be reinstalled on the machine you had installed RSC on. You can also try installing RSC to another IIS Server.
