When using System Center Configuration Manger 2007 R2 (SCCM) with Intel vPro/AMT technology, there’s two stages to the provisioning process.  In the second stage the SCCM server attempts to connect to the device that’s being provisioned.  This can fail if the SCCM server has a proxy configured without the required proxy exceptions resulting in the error below:

Error: Can not finish WSMAN call with target device. 1. Check if there is a winhttp proxy to block connection. 2. Service point is trying to establish connection with wireless IP address of AMT firmware but wireless management has NOT enabled yet. AMT firmware doesn’t support provision through wireless connection. 3. For greater than 3.x AMT, there is a known issue in AMT firmware that WSMAN will fail with FQDN longer than 44 bytes. (MachineId = 11578)

From the command prompt enter  “proxycfg -d” to bypass the proxy.  Alternatively, open IE, set proxy server, tick “Bypass proxy server for local addresses”  and enter *.%YOURDOMAIN%. Next, from the command prompt enter “proxycfg -u”.  This import the proxy settings from IE.
