During my lab setup of SCCM and trying to get Agent Initiated Provisioning to work for a vPro system, I was running into a basic issue of the SCCM agent being able to auto-discover the SCCM Site Server.  After installing the SCCM Agent on the vPro system, I would initiate, from the vPro Client, Control Panel > Configuration Manger > Advanced Tab > Configurations Settings > Discover Button, and would receive an error that the client was unable to discover the SCCM server.



So I started looking at the SCCM Help file.  I ran into the section about extending the active directory to enable this site discovery (http://technet.microsoft.com/en-us/library/bb633121(TechNet.10).aspx).  But not only do you need to extend the active directory, you also need to Create the System Management container, set security permissions on this container, and enable Active Directory publishing for the Configuration Manager site to this container.  These steps will allow clients to automatically detect the server locator points and management points (which must be added to your SCCM Site Server). 



After following these steps, I was able to immediately discover the SCCM server with my Agent installed on my vPro system.  Now I can move on with the AMT provisioning process.



TechNet also provides alternative steps that allow you to update your WINS environment without extending the schema and/or publishing this information to the System Management container.  You will need to determine if this WINS update is acceptable for your environment or extending the AD is the right solution (see link below).  I'm curious on feedback from the community if the updating of WINS would be acceptable in your environment and what issues this would create.
