Novell ZENworks 10 Configuration Management


If the ZENworks agent is deployed to a device using the same IP address as another discovered device, both devices will attempt to register using the same GUID.


Discovery and push deployment assume unique IP addresses on resulting device.

Additional Information

This was seen in an environment where all devices were imaged using the same IP address and computername.  Then discovery and deployment were run to push the ZENworks agent.  After that, the IP address and computername were modified after deployment.  In this case, the machines received duplicate GUIDs.
If the IP of a device is changed after deployment and registration, and the previous IP is going to be used for another device for Discovery/Deployment,then it is better to delete the IP entry.
  1. Go to ZCC, Devices > Discovered >All Types and delete the device with the IP that is going to be reused. This will clear the IP entry in NC_NetworkDeviceBase .
    Then it is possible to do a discovery of this IP, which will ensure a new NetworkDevice OID (Object IDentifier), which will be later sent as the GUID during deployment.

  2. Do a Deployment without using discovery to this second device by IP.
Either way, a new GUID will be used.
