Hi Musketier,
Apologies for the delay in response as I've been away on vacation. Your result is interesting as we were able to duplicate what you were seeing. There are a couple more things. First, I notice that the AMT version is updated for SA-00075. What version was this running before that?
Second is something I'd like to confirm. I know that you are in Admin Control Mode but need to see if "User Consent" is enabled. An easy way to check this is to download and install Intel Manageability Commander, located here:
https://downloadcenter.intel.com/download/26375/Intel-Manageability-Commander
configure for the system you are connecting to, connect and on the "System Status" screen, there is an item "User Consent". Can you tell me what it is set to?
It should look like this:
