One thought I had to your particular problem: Did you run the loadcert utility that installs with SCS? You will find information about this utility on page 60 of SCS User Install Guide. You run this utility and select either the Verisgin Cert or Internal Cert you may have setup for Remote Configuration.
Steps from the User Guide:
Invoke the loadcert utility, located at <install_root>:\Program files\Intel\AMTConfServer\Tools. Double-click on loadcert.exe. Select the certificate that was just imported. The utility will report any problems in the certificates that it detects that would prevent using it as a Remote Configuration certificate.
You know I don't think I have. I believe when I read that you needed to contact once of the vendors whose root cert hashes are in the AMT firmware, I passed the section up. We have an internal CA but it appeared that you needed one of the vendor's hashes that are in the firmware.
Went ahead and ran the loadcert.exe and selecte the machine cert that I had created earlier and it appeared to load without any squawks. I restarted the demo machine and now I have a new message in the log! Something different. Now it says
No rows found in get Configuration Parameters.
Well, OK, I'll manually enter the UUID and see how that goes!
