Power Operations Fail With a Provisioed Computer

[idata]

Hi experts,

I have a vPro client computer with AMT 4.0. It was importeed successfully via the Import OOB Computers wizard, and after sending a "Hello- packet" it became provisioned. (The SCCM GUI displays AMT Status: Provisioned).

But when I try to perform power operations on this machine, they always fail with the following lines in the log:

AMT Operation Worker: Send task amt4.domaindemo.com to completion port 7/29/2009 10:59:29 AM 2176 (0x0880)

I've try to access this machine via Web - UI (https:\\amt4.domaindemo.com:16993) and the Security Alert says that the certificate is valid. Despite that, I get a "Page not found - Web browser access to AMT is disabled on this computer, or the page in the address bar is unavailable" page!!

What should I do???

Thank you all in advance - I hope you have a quick answer, this issue is quite urgent for me.
