So I'm doing some imaging testing with an IBM laptop, and I am using the zisedit command to change some options in the image safe data. This is a laptop that has not had the Zenworks Agent installed on it yet. When I try to edit the field DNS Hostname, or any other field for that matter, I'm not able to!

I try to change the values under the Network Information section, and when I hit "Save" to apply my changes, the fields just stay blank or say "Not found." I was able to edit the image safe data on another laptop of the same model. If anyone has an idea of why this is happening, please enlighten me.
Thanks for your help in advance.
