House70: All the administrator accounts are locked out.
Sub mesa: booting with ubuntu still wouldn't allow me to change/unlock the administrator account.
All: I have gotten my hands on a Microsoft ERD Commander disk that will allow me to boot in Windows and change/unlock the administrator account. Will try this today. Should work.
@ ryeg : I am having the same problem with Server 2003 on a SAN controller. The Ultimate Boot CD (on a USB key) won't find the system hard disk. Did the ERD work for you? Did something else work for you?
