Lost Administrator Password for Windows 2003 R2 Enterprise Server

I am trying get an unused server up and running, it booted fine but i was greeted with the login window and none of the known passwords seem to work.
The server I am trying to get to work is not a Domain Controller and has not been used in a long time.


OS: Windows 2003 Server R2 Enterprise Edition


I tried Ophcrack XP (there is no WinServer version of Ophcrack) - it couldn't locate the partitions with hashes. I tried mounting the partitions myself (#mount /dev/hda*x* /mnt/ntfs), but it gave me an error saying /dev/hda*x* didn't exist.


Next I tried booting into a Ubuntu 10.04.3 LiveCD so that I could install and use chntpw - no go, Ubuntu Live wouldn't boot.


Based on what I've read up the following tools may be of help:



  1. Windows Password recovery

  2. Petter Nordahl-Hagen's Offline NT Password & Registry Editor

  3. Openwall's John the Ripper

  4. EBCD – Emergency Boot CD - Bootable CD

  5. (R)ecovery (I)s (P)ossible Linux rescue system


I am hoping that someone here has prior experience with Win2k3 Administrator password resets so that I don't end up having to try all of the above to find out which one works.
