Problem w/ Remote web workplace - remote desktop active X control

I have installed Internet Explorer 7 and I am getting an error each time I try to run /install the terminal services active X client. I click on install and then I get an error message then when I try to connect to a machine then I get the Active X message again that I need to install the active client. Can anyone tell me different way to install this or possibly is there a problem with my settings or possibly being to restrictive to install this Active X? Thanks for any information.

To resolve this issue, an organization that hosts the secure Web site can purchase a certificate for each Web server from a third-party provider. Or, the organization can install a Microsoft Enterprise certification authority in the Active Directory forest. Then, the organization can use this certification authority to generate a certificate for each Web server. More information here - http://support.microsoft.com/?id=931850
