As noted in a previous blog, SCCM SP1 only natively supports vPro firmware version 3.2.1 and higher. For legacy (less than 3.2.1) vPro clients to be supported, SCCM SP1 depends on the WS-MAN Translator.
There has been an issue identified within SCCM SP1 (RTW version) Out of Band Console that does not route AMT management communication through the WS-MAN Translator for legacy systems. Microsoft is aware of the issue and will be releasing a SCCM SP1 HotFix (targeted for July’2008) to address the problem.
Provisioning and collection based (power control / WOL via AMT) are not impacted by this issues; vPro firmware version 3.2.1 and above are also not impacted.

So what's the impact for the OOB management? Do all of the OOB functions does not work for the legancy AMT machines?
