AMT provisioning keeps failing.

[Jools86]

I have 2 PCs. One is provisioning fine. The other constantly fails.

Successful:

Failure:

(from Manageability logs):

On the failed machine, I get this INVALID_STATE message, on the FAILED machine AMT is de-provisioned, I am struggling to work out why this is happening.

Both machines have the same build. I have performed the following on the machine which wont provision:

• Installed IME drivers
• Re-provisioned / De-provisioned AMT via BIOS / ACUConfig multiple times
• Failure Machine has same DNS suffix and DNS / IP subnet as Successful machine

But for whatever reason this machine wont provision. I have even Disabled and re-enabled Manageability features witin MEBx but to no avail.

Any pointers as to what "INVALID_State" could mean?
