Dell GX620 - ZISEDIT not saving ?

Been messing with a new image on this Dell GX620 machine. Installed
the Zenworks Agent and realized that nothing is getting saved in ZISD.
I opened ZISWIN.exe and gave the computer a "NETBIOS" name and a "DNS
HOSTNAME" closed it, everything looked good.. hit Save, etc. I go back
in and its gone. I booted to PXE and ran ZISEDIT, did the same thing..
as soon as i hit SAVE it goes back to the "view" screen, nothing is
set. I changed the hard drive to COMBINATION mode for SATA, tried it
again... same thing! whats the deal?
