Cloning the disk image with Agent installed

During installation, nVision Agent generates and saves its unique GUID identifier in the registry. If the Agent detects the change of machine SID, where it is installed on, it generates a new GUID during startup. The correct sequence of steps should include the preparation of the operating system with SysPrep utility before cloning the disk image to other machines. In such a case, when starting each cloned system, a new unique SID is generated, and Agents from these systems report in to nVision with different (unique) GUIDs and thus they create separate icons in nVision. Otherwise, each system reports to nVision under the same GUID, i.e. a few Agents send their data to the same icon in nVision.

If such a situation occurs, use SysPrep utility to reset SIDs on individual machines:
