Never used backtrack4 for password cracking have only used it for wep/wpa-wpa2 cracking. I use OPHcrack for passwords and trinity rescue for passwords. So if you replace all the grep admin/root/adminpassword with the name of another user account like grep tommy /root/tommypassword. Would it then crack that password?

adminpassword (tommypassword) it is just filename. Name it whatever you want.

E.g

cat /root/list | grep Tommy /root/Crocodile

@jathenanda Not sure why it will not work I follow the steps you have layed out and it gives me this "No such file or directory" when I enter in mkdir /mnt/sda1? But if I skip that step and enter in mount -t ntfs/dev/sda1/mnt/sda1 and hit enter it works and root@bot shows up again. But them for Cd/mnt/sda1/windows/system32/c­onfig it give me the same thing "No such file or directory?

@jathenanda

Probably your disk isn't SCSI, but it is IDE. Try to use hda1 instead of sda1.

If you have more than one disk, then it can be hda1 or hda2 or hda3 etc...

If you are using "real machine" (not virutal), sometime windows partition is automatic mounted (to check this, type cat /etc/fstab. In that case you don't need to use mount command.

If windows partition is NOT mounted and you dont know which partition is correct one, then you can use cfdisk command.

@jathenanda Hda1 one worked all the way up to cd /mnt/hda1/windows/system32/con­fig it kicked back the "No such file or directory" I then tried hda2/3 and so on with the same message. Any ideas? Not a huge deal as I can still run OPH or rescue to crack it but it would be nice to have a nother new tool all in one. Thanks for the help/reply's so far.

TIP: It's case sensitve... DO NOT type "windows", type Windows .)

Obviously, windows folder is not there where it should be. Type

locate Windows

Previous command should locate your windows folder (if it is mounted)... When "locate" command finds windows folder, use that path instead /mnt/hda1/windows
