A device is automatically unregistered when the ZENworks Agent is uninstalled. You can manually unregister a device if necessary.
Unregistration of a device can be done at the device using ZENworks Agent command line utility (zac):
At the device, open a command prompt.
Enter the following command:
zac unr [-f] [-u ZENworks Administrator username -p ZENworks Administrator password]
zac unr -u zadmin -p novell
The -f, -u, and -p parameters are optional. If you do not use the -u and -p parameters, you are prompted to enter a username and password. The -f parameter ignores the ZENworks database and forces the device to be unregistered locally; this option is only necessary if the device object has already been deleted from the ZENworks database or if the device cannot connect to the database.
To manually unregister a device, do the following:
Log in to ZENworks Control Center.
Select eitheror as the type of the device, then select the devices you want to unregister from the Management zone.
