Reset NT/2000/xp Password ?

Hey guys,

I saw this advert on ebay here :

http://cgi.ebay.co.uk/ws/eBayISAPI.d...tem=3404332915

which claims to do this :

Forgetting a password is one of the most annoying things that can happen and waste hours of your time guessing it or reinstallation of the operating System. This disk will enable you to change/reset the password of any user (including ADMINISTRATOR) on a Windows NT, 2000, XP installation WITHOUT knowing the old password. This disk is able to actually parse/follow the internal registry structure completely. It also handles (disables) syskey. You may either let the scripts try to figure out your configuration or you may do it manually from the shell prompts.

FEATURES:

100% recovery rate
Windows NT3.51 & NT4 Workstation, Standalone Server, PDC.
Windows 2000 Professional, Server and Advanced Server (not with Active Directory Server)
All secure boot options are supported
All Service Packs are supported
Windows NT, 2000 or XP setup CD-ROM or floppies ARE NOT REQUIRED



I wuz wondering, is this possible ? Has anyone tried it ?

:confused: Dr_Evil

I don't know.. sounds fishy..

But I could make you a linux floppy to do the same for any linux box :D

after boot there'll be a script asking to mount the root partition.. then it'll ask which usernames you want de-passworded...

then it opens /etc/shadow

and removes the password has..

tada a next reboot no passwords !!

There is a similar one that does that to a NT/2000 box (not sure about XP). Using Linux it modifies the SAM and thus let's you reset the password.

In fact, that link on Ebay looks like the instructions for http://home.eunet.no/~pnordahl/ntpasswd/ . Note: I do not advocate the use of this. I use this as part of a lab I run in a course I teach. If you decide to use it, it is AT YOUR OWN RISK. I've had students foo-bar their Win2K installs with this.

i have a similar older disk that needs to be booted. it only works on win 9x and 2000. but its still good. will look at this one lster and tell you how it goes.

yess .. that ever happened to me mate, and i was so scared about that . becoz i can enter my own computer ( i forgot my password ). i try to reboot by CD and repair it and it still ask the password.
have u try to install it by reboot from cd and make a refresh installation ?
and when it ask you to format the NTFS or Fat32 .. just choose "leave the curent " and it will reainstall ur OS.
i know it is not the solution .. becoz at that time i don't know the sollution either. but let me give u an advice ( from a newbie ) .. always make more than one admin account on your system . i did that till now .. so if u forget you still have the other one.

i could be wrong but i've trid mate.

:)

<edit> if anyone gets a hold of this disk, are they able to pass it on to me for study </edit>

have you try the safe mode ? perhaps it helps u .. ( press f8 at the first boot )

:)

For lost passwords, I use ERD Commander by Winternals. http://www.winternals.com/products/r...mander2002.asp

It's actually a pretty cool tool for other things too. You can get a 30 day evalutation copy to check it out.

For lost password, you can also use Cain (http://www.oxid.it).

See if this helps

Most of these are bootable floppies that give you a backdoor to the SAM registry hive and allows you change the admins password.

Run it to create a boot floppy then follow the instructions. If you choose to do this then you are doing this at your own risk. Just change the admin pw and login then change the account pw's that you desire.

Make sure you have a floppy disk in the floppy drive and let the program create the boot floppy. Now restart the machine a let it boot from the floppy. Now follow what it instructs you to do.

Use it like a bootdisk.

Windows XP / 2000 / NT Key is a program to reset Windows XP / 2000 / NT security if Administrator password, secure boot password or key disk is lost.

Or you could, if you have a FAT32 file system, just boot to a Win98 bootdisk and rename the SAM file (registry Hive) in the C:\WINNT\system32\config folder to something else. Of course this will remove all accounts on the system and you will need to rebuild them. If you are using NTFS then boot to the Win2000 CD and do this from the Recovery console.

NTFSDOS might be usefull too http://www.sysinternals.com

:george: Well , Thanks to all of you,


I didnt expect this thread to turn out to be educational.Perhaps we need a tutorial on how to create one these disks, here on Antionline.Would be very handy for newbies.



Dr_Evil

The one that MsMittens mentions is just the job. It is not a trial version, or crippleware/ shareware/ commercialware, but entirely free to use.

If your Windows NT/2k box is installed on a NTFS or FAT partition on a normal(ish) IDE or some SCSI discs, then it will work.

I have used it on a number of occasions without any data loss (that's no guarantee that it won't hose your box)

Windows XP's Forgotten Password Wizard helps create a Password Reset Disk that you can use to gain access to your computer if you forget your password.

There are different steps, depending on your computer's connection to the network and the type of account you have. For example, follow these steps if your computer is on a workgroup and you have an administrator
account:

1. Open Control Panel and the User Accounts tool.
2. Click your account.
3. Within Related Tasks, select Prevent A Forgotten Password.
4. Follow the instructions provided by the wizard.

If you have a limited account, simply skip step 2 in the instructions above.

If your computer is on a domain, perform these steps:

1. Log off.
2. Press [Ctrl][Alt][Delete].
3. Click Change Password.
4. Select the local computer in the Change Password dialog box.
5. Click Backup.
6. Follow the instructions provided by the wizard.

When you log in to this computer that's on a domain and receive a Logon Failed error message, just click the Reset button to launch the Password Reset Wizard. If this computer is on a workgroup, you'll see the message Did You Forget Your Password? Click Use Your Password Reset Disk to launch the Password Reset Wizard.

Keep in mind that the Password Reset Disk only works on the computer on which it was created. In addition, within a domain environment, the Password Reset Disk will only allow you to gain access to the local computer. You'll still have to ask your domain administrator to change your domain password in order to regain access to the network.
