AMT Configuration issue, HELP NEEDED

Hi All,

When trying to run a delta configuration from the client pc using the following command ;

c:\Configurator>ACUconfig ConfigViaRcsonly ****** DeltaProfile /Adminpassword ***** /WMIuser *******\******** /WMIuserpassword ******

I get the following error in the log;

2013-07-30 13:29:17:(INFO) : ACU Configurator , Category: HandleOutPut: Starting log 2013-07-30 13:29:17

2013-07-30 13:29:41:(ERROR) : ACU Configurator, Category: Exit: ***********Exit with code 75. Details: Failed to complete remote configuration of this Intel(R) AMT device. A Service Principle Name (SPN) registration error occurred.  DsBind: 1727 (0xc0003a9d). The RCS failed to process the request.

Not too sure what I'm doing wrong here.

Any help with this would be appreciated.

Many Thanks in advance.
