When you are running the Remote Control Utility from your workstation, are you sure that the workstation is able to verify the server certificate that the AMT system was provisioned with? If you have the WebUI enabled on the AMT system, you can verify this by opening a web browser to 'https://<hostname>:16993' to see if the certificate is trusted. Otherwise, you can add the following switch to the command line when using the Remote Control Utility: -ignorecert. While not documented (yet), this will allow the utility to ignore server certificates that are returned from the AMT system.
