Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.1 Deployment


Workstations are taking ownership of the same or duplicate GUID during agent deployment.  This happens when a USB or thumb drive is used for deployment of the agent. 


This is fixed in version 10.1.3 - see KB 7002526 "ZENworks 10 Configuration Management 10.1.3" which can be found at
Additional changes have been made in 10.2 to detect when this issue occurs.  Logging has been modified to reflect if a device host name has been changed or if a device has been renamed.  This will make it easier for administrators and support personnel to discover when this issue has occurred. 
This is fixed in version 10.2 - see KB 7003225 "ZENworks Configuration Management SP2 (10.2)" which can be found at

Additional Information

In this case,  A thumb drive was being used to install the agent on multiple devices.  Image safe data (ISD) was being saved to all local drives including the thumb drive, this is how the ISD of the first device ended up on the thumb drive. Then when the newly installed device registers, the ISD is not found on the internal hard drive but on the USB thumb drive and are using the GUID from the ISD. The issue only happens if the ISD is empty, which is the case when ZISWIN shows "No image-safe data on this machine". In this case zisd lib went to the next drive and if it found ISD on the removable drive, the code path was using it and duplicating the GUID.
