I finally got my pxe-boot kickstart enviroment to work but during the process I had a few mistakes.
At one stage I aborted a PXE-initiated Kickstart install because of an error in the preboot bundle. However this device now wont PXE-boot again - according to /var/opt/novell/log/zenworks/prebootlookup.log "Assigned preboot work is already done". This device doesnt appear in the list of devices in the webGUI so I cant assign it.

When I do '/etc/rc.d/init.d/novell-zislnx dump' on the server it shows my device

Is there a way reset this device so it will re-run the initial kickstart install again?
