When I have local access to a computer running Windows NT (or 2000), is it
possible to delete or reset or whatever a lost Administrator-Password?

I think it's only possible if your user account has administrator
privledges. AFAIK, only Administrators and the owner of the account (if
the account is configured this way) can change account passwords.

You can reset the password with a NT utility from www.accessdata.com.

It is possible to change the Admin password...without even knowing it. All
you
need is local, physical access. The key is a Linux bootdisk that has a
program
that changes the binary data in the SAM...passwords. Do a search on
"ntpasswd"

Well, devious means aside... I assumed the original poster was looking
for a way to do it through Windows itself. :)

Deviousness isn't an issue. The OP said that he could sit at the key board
(physical
access) but had no passwords with which to log onto the system. Given
that, how would
you expect to use Windows itself? Hint: L0phtcrack will NOT work...

That was exactly my point. It can't really be done via Windows. I was
assuming the attitude of "Our admin left the company without telling us
the password", and not one of "I can get at the server every day when
my boss leaves at 4:30, so how can I change the password." That was
what I meant by "devious".

Maybe I'm just naive. End point was that via Windows itself, if you
forget the Administrator password and don't have any other user
accounts with admin access, you're up the proverbial creek without the
proverbial paddle.

You can find such a paddle at
http://www.sysinternals.com/
look for NTLocksmith

OR

run L0phtCrack on the ERD diskette (you do have one, don't you?)

OR

boot a DOS diskette and use NTFSDOS

No, you're not...

I've used it several times, and it's worked like a charm.

Well, if I have an account, I think it's no problem to get admin privs.
There is a program called getadminsrights, isn't it?

Ok, stupid question, and in the wrong group: I used Linux, of course, but is
it possible to make a disk, that can boot up a running linux system? How?

You're absolutely right.

But if I use Win or a Linux Bootdisk doesn't matter.

Yep. There are Linux distributions where the *entire system* fits on a floppy
(muLinux, for one).

> How?

Depends on your distribution. If you look through your Linux docs, there
should be instructions somewhere for building an emergency boot disk.

The link http://home.eunet.no/~pnordahl/ntpasswd

provided earlier by poster HC is f r e e where
Accessdata.com's products likely aren't.
This product does work if you know the path to the winnt
folder (assuming it was named that during the install (the
default name) and then the SAM files can be found. The
Linux shell script in the above link will offer defaults to
the SAM - you will have to key in the correct path if your
install is other than a default. It will then allow you to
change the password for an account - it does not and will
not (to my understanding) reveal current passwords to you.

A product like L0phtcrack or the above Linux boot disk is
only a "devious" tool if used for a "devious" purpose. Used
legitimately, it is a very legitimate tool that can save an
over worked Admin's behind in a "lost the Admin account
password amd re-building this machine is out of the
question" situation. It's kinda like a hammer that can be
used to build or to bash - so what kind of tool is it?

The Linus disk will also work with Windows 2000 assuming
Active Directory is not activated. Also know that Linux
command line scripting and feedback is different from
Windows/DOS. You may have to learn some rudimentary stuff
about Linux to follow where the script is taking you.

Hope you get out of your jam.

& this only works on WinNT4.0 but not with Win2K Pro & Win2KAS.
I have tested it out before too.

Hi, Well hard to say about if you can recover the administrator data or not, But yes i can assure you that with a third party tool you can do that.

Please test Lepide Active Directory Self Service for the same. This tool will help user to self update his account and password on his own.

You can download the tool from the given link and update how it works..

http://www.lepide.com/active-directory-self-service.html

Hope it works fine for you and please update if it helps you.

Thanks.
