    Default Windows passwd crack

    I need help resetting the password on my old laptop (Acer Aspire 3100-1718). Even though i followed all the instructions; somehow, i'm still unable to reset the password. Can someone plz take a look at this and tell me what i'm doing wrong?
    Thanks

    PS: this is how it looks like

    1- ls /mnt/sda2/Windows/System32/config
    2- mount
    3- umount /dev/sda2
    4- mount -o rw /dev/sda2 /mnt/sda2
    5- cd /mnt/sda2
    6- ls
    7- cd Windows/System32/config
    8- ls
    9- cd /pentest/password/chntpw
    10- chntpw -i SAM
    i even tried: lower case "sam"
    chntpw -l /mnt/Windows/System32/config/sam
    and
    chntpw -i /mnt/Windows/System32/config/sam
    either way i'm getting the same msg:
    openHive( SAM) failed: No such file or directory,tying read only
    openHive( SAM) in fallback RO-node failed: No such file or directory

    You care to give a version of windows you are using?
    Might also be easier to use the oem cd that came with it.
    To be successful here you should read all of the following.
    ForumRules
    ForumFAQ
    If you are new to Back|Track
    Back|Track Wiki
    Failure to do so will probably get your threads deleted or worse.

    wutz up phen1x, i know i'm a noob but i think i can help just open a new shell in backtrack and type the following:

    cd /mnt/sda2/Windows/System32/
    mv Utilman.exe Utilman.backup
    cp cmd.exe Utilman.exe

    Note: your hardrives name may be different so you should change that mine is sda2

    and then reboot now go to windows logon screen and hit the windows button and the letter U it should bring up an administrators cmd then type

    net user (your username) *
    and type new password


    hope it helps

    From what I can see, the path you gave chntpw is wrong.

    Code:
    root@Intelligence:/mnt/sda2/WINDOWS/system32/config# chntpw -i SAM
    chntpw version 0.99.5 070923 (decade), (c) Petter N Hagen
    Hive <SAM> name (from header): <\SystemRoot\System32\Config\SAM>
    ROOT KEY at offset: 0x001020 * Subkey indexing type is: 666c <lf>
    Page at 0x7000 is not 'hbin', assuming file contains garbage at end
    File size 262144 [40000] bytes, containing 6 pages (+ 1 headerpage)
    Used for data: 272/22312 blocks/bytes, unused: 5/2072 blocks/bytes.
    
    
    * SAM policy limits:
    Failed logins before lockout is: 0
    Minimum password length        : 0
    Password history count         : 0
    
    
    <>========<> chntpw Main Interactive Menu <>========<>
    
    Loaded hives: <SAM>
    
      1 - Edit user data and passwords
      2 - Syskey status & change
      3 - RecoveryConsole settings
          - - -
      9 - Registry editor, now with full write support!
      q - Quit (you will be asked if there is something to save)
    
    
    What to do? [1] ->
