For general questions about Remote Configuration, please review the following article - http://communities.intel.com/docs/DOC-1490
Earlier in 2007, I wrote two brief articles about Remote Configuration.
The embedded video below is a summary of how Remote Configuration works in an Altiris environment. The target environment has a VeriSign Intel(R) Client Setup Certificate loaded. Intel AMT 2.2 and 2.6 systems are provisioned using Agent Initiated approach. The Intel AMT 3.0 system is provisioned using the baremetal approach (could have done this via agent initiated... yet wanted to show both methods)
More content\details on acquiring external certificates, or creating a custom internal certificate and adding the associated certificate hash to the clients... can be provided if needed.
