System Center Config Manager Task Sequences (SCCM). Version: 1610 Mostly used for deploying Operating Systems through SCCM, these cheeky guys bring some fresh hell to your learning burden.

The objects referenced in the task sequence cannot be found. Verify that the objects exists and that the task sequence references the correct object name and location.
