For those of you who are having issues with the x64 architecture, I recommend installing the NEWEST version of the software and following the directions from the ntpasswd website here:

Good luck and happy hacking.

When i click reload i get a message that they cannot be found…. (for some reason this computer will connect to the wireless network by using a password but will not get on the internet and i suppose because of permissions it’s not visible on the other computers.) I’m using Ubuntu to accomplish this. Ubuntu is not installed it’s live. How do i get the thing on the internet. Again it’s connected to the wireless network and has a very good connection

For those with issues on x64 systems,

Try using the ubuntu-x.xx-desktop-i386.iso to reset passwords. It worked for me.

Worked a treat for me booting from a USB stick running crunchbang linux. I couldnt use the sudo chntpw SAM option but i was able to use the sudo chntpw -u SAM. I tried setting the password which didnt work, but choosing the option to blank the password worked perfectly

Thanks Ubuntucat!

Hey download the sourcecode and use chntpw.static if you are on xp x64. Cheers.

As soon as I type “sudo chntpw SAM” I get this:

ubuntu@ubuntu:~$ sudo chntpw SAM
chntpw version 0.99.5 070923 (decade), (c) Petter N Hagen
openHive(SAM) failed: No such file or directory, trying read-only
openHive(SAM) in fallback RO-mode failed: No such file or directory
closing hive SAM
Unable to open/read a hive, exiting..
ubuntu@ubuntu:~$

Can someone help me?

I just tried this procedure with an old (at this point in time) Ubuntu 8.10 live disc. When I tried to install chntpw using Synaptic, no results were returned from the search. My newer (permanent) Ubuntu system’s package manager was able to find chntpw, however.

I tried a couple of other searches, and was about to manually edit the repository list files when it occurred to me to try apt-get. I opened a terminal window and entered

sudo apt-get install chntpw

and it was able to locate and install the program. (Apparently chntpw was there but had been deselected). When I mounted my XP partition and ran chntpw to blank out my own account’s password it worked like a charm.

So, if Synaptic doesn’t find the package, try going into a terminal and using apt-get (you’re going to need to open a terminal window anyway).

Thanks!

Ok, fixed. User error, as normal. Got all the way to the use of the chntpw. it gives me 5 options, and the first says to blank the password. I chose 1. then accepted all the prompts, and backed out. When I reloaded XP, it still said my password was in effect. it didn’t work. I’ve tried it three times now and I can’t get it to work. It doesnt look the same as what you have pictured, but it still tried to implement. not sure what I’m doing wrong, but I am a lowly Windows user, not a linux ninja, and all I can do is look around and beg help.

Hey. Brand newbie. Just downloaded Ubuntu, because a friend told me I could do this. But I can’t find chntpw. I tried searching for it, but nothing is around. Help! Computer fubar at the moment! Need this to work!
