This problem is caused by an issue with the Systems Management Server (SMS) Agent service when stopping the Windows Management Intrumentation (WMI) service. When you have WMI Framework 3.0 installed, this will request the WMI Service to rebuild its repository, causing the WMI service to shut down, stopping the OfficeScan NT Listener Service.

To resolve the issue, upgrade to System Center Configuration Manager (SCCM) 2012 Service Pack 1.
