I have an iomega nas (nas 400r) - it runs windows 2003 "appliance edition", looks just like windows 2003 server, not sure what it does differently. Anyway, need to reset local admin password. I have tried konboot and the ntoffline one but neither one have the correct drivers for the raid (adaptec of some sort). I DO have the correct drivers from iomega, but they are for windows only.
I was able to slipstream the driver to a win2k3 cd and install a parallel OS of win2k3, if that helps.
I believe the administrator account is locked by now, there is another local admin account called pbadmin but its not accepting the password either. I obviously have physical access to the box - it runs raid, no linux drivers to my knowledge...
