I just did a test in which I unprovisioned my HP DC7700 and Intel DQ965GF clients via the SCS Full UnProvisioning option. The clients unprovision correctly, however the problems start when trying to re-provision these clients. As the full unprovision is supposed to be a total reset I expected the clients to be re-provisionable by simply putting a correctly configured USB key into them and then restarting, this should then load the key pairs etc. and the client should re-enter its provisioning cycle.
The problem is that the Intel clients do noteven attempt to read the new keys and the HP system complains that the default password for the ME BIOS extension is incorrect.This is the same problem i have experienced before when trying to return the AMT settings to the factory settings through the BIOS options; I had hoped that unprovisioning with the SCS may be differant.
This is a serious problem and i need to know if there are any plans to fix this in the future. My current AMT firmware version is 2.1.4
