How would I change IP address (and Subnet Mask & Gateway) a couple (60)
of workstations by remote with ZENworks?

1. Take a Remote Control to each workstation and Remote Execute Ziswin.
In Ziswin -> Modify Image-safe Data -> Just Imaged Flag = True and
change IP Settings. And Save Image-safe Data and reboot the workstation.
ZENworks Management Agent changes the IP settings.

or

2. Make a New Object with Console One. New scripted ZENworks Image
object. Script text:
zisedit JustImaged=True
zisedit IP=10.20.30.11
zisedit Gateway=10.20.30.1
zisedit Mask=255.255.255.0
And linked this ZENworks Image object to registered workstation object
(ZENworks Imaging - Put an image on this workstation on next boot - Use
this image ... session).

or

3.???

Is there other way how is possible to change IP address etc by remote?
