XP PRO password forgotten! How to fix? Subject description: The only account in it (Administrator) has a pwd but it has been forgotten... |
|
...after many month without been even turned on due to a damaged screen.
I happened to make that old pc start again after finding a screen & reinserting the RAMS. That's not my pc but it's needed in a car shop because it contains very useful program inside (don't know what program).
I've read about ophcrack & it should run under linux. Where I can download it to try to see if I finish this issue?
PS. I've read about other alternatives that 'erases' the pwd in a windows installation, which makes me think about the possibility of running Puppy, for ex., getting access to that SAM file & erase the pwd location's contents. I know, this's the riskiest method but, can it be done like so?
Thanks to any that has some useful info on this!
PSS. I know the owner & that pc has been his since 2003.

@benny7440,
1)Ophcrack is a distro itself,not an app!
2)Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow ... Free tables available for Windows XP, Vista and 7.
go to http://ophcrack.sourceforge.net/download.php?type=livecd
choose yours.
burn to disc/usb pen.
done.

It has occured to me that since that machine is trying to boot WinXP PRO I might be able to intervene with its menu.lst file & dual (or triple) boot it, been Ophcrack one of them. I don't know what caveats the PRO version would have for doing this but any ideas are welcome.
As far as I understand it Ophcrack should be considered an OS in itself & that's why cannot be run as an ordinary api: is this correct?
Thanks to both of you for your replies!

you can use PupRescue Precise in order to delete your xp password using chntpw
First mount your XP drive and then type the following into a terminal
chntpw -i /mnt/sdXY/Windows/system32/config/SAM
*windows may be WINDOWS or Windows depending on your system
*system32 may be with a lower case s or uppercase S depending on your system
*X is the drive letter and Y is the drive number
From there just follow the instructions in the terminal

I've used this many times and it works, although, a newer comp with a SATA drive might need drivers which should be available from the same site.
Have you tried to log in as administrator with a blank password? You'd be surprised how many times it works.

Thanks DPUP5520, rg66 & cthisbear for replying!
To DPUP5520: Your solution seems to be very complete but, just for removing a Win XP pwd, I was thinking that even a little program in a 3.5" diskette might do --could be wrong on this!
To rg66: The only acct. available there is the Administrator (with an unknown pwd) &, yes, I tried it many times already. I think I'm inclined to try the 'pogostick' method first.
To cthisbear: I think that many years ago I read about it & it looked then very good, now it looks even better. The problem is that it's a too powerful tool for the job. I strive to keep things as simple as possible. That's why I inquired above about manually editing the Registry ...

You can get chntpw on the puppy package managers on Slacko or Lupu, I think.
Icyos made a youtube tutorial on this.

Thank you for replying, dk60902!
I used the PPM (PL 5.2 & didn't find chntpw in there. I'm almost sure that someone here has made a version fit for Puppy 5 series already. It's located somewhere onknown to me though, unless Puppy can use a version located in an Ubuntu repository (which I'm not very sure, yet).
Since the Win machine is away from my place & there's no internet connection I need to locate the app, download it to a pendrive and, once I get there do you think I can use either a PL 431 Live CD that boots there as well as a bootable DSL pendrive that also boots there to run that app?
Note: DSL uses Knopix.
Thanks for any thoughts/ideas!

If you're running Puppy Precise just type "ophcrack" into the ppm in install the app from the Ubuntu-precise-universe repo.

Thanks for replying, kurtdriver!
To be precise I'm running PL 5.28.005 now. It's the newest version I've.
All this is happening within a VAIO notebook, so I don't have access to a diskette as the machine to be healed has for other options available.
BTW, from where I can get the 'chntpw'?
Could 'ophcrack' be run within a pendrive if I'm using PL431 live cd? I mean, if I can d/l it in a pendrive here, take it to that machine, run PL431 there & then use ophcrack from the usb there to solve the issue?
Thanks for any info/ideas!
Edit: It has occured to me the possibility of running, say, PL431 from the live cd there, shrinking the partition that Windows occupies now & to 'put' in that new partition, say, ubcd, BartPE or something else useful for dealing with this issue; then, edit the menu.lst file in windows as well as the boot file there to make it a dual (triple?) boot system...
If it can be done (there're many variants to do this) then there's the issue of 'what to extract from the iso file & where/how to put it in order to enable it to boot' --workable.
Do anyone here has an opinion in favor of this approach or else?

If I remember correctly, I found it in Lupu 5.2.5, and Slacko 5.3.3. I couldn't find it in 5.28 despite IcyOS's tutorial showing it.
You can always download Hiran's bootcd. There is a password recovery utility.

You could run either of those programs from a live cd, without re-mastering. Boot up, download the program and run it. It all sits in RAM, so when you reboot it's gone.

I don't think you understood, sorry I didn't catch it yesterday, "Puppy Precise" is a version of Puppy that can access the Ubuntu repos. Ophcrack is the repo I listed above. Good Luck!
