recovering password from another w2k on the same computer

[aa]

I have forgotten the admin password (the only account set on this
installation) on w2k Pro.
I have another w2k Pro installed on another partition on the same computer.
Is there a way to recover the password from that second w2k installation?
Where exactly the pw is stored?

 

[aa]

Thanks, Pegasus
Will this affect my second w2k installation on this computer?

No, you cannot recover Win2000 passwords. They
are stored in a file called SAM and they are encrypted.

You can reset the admin's password to a blank with
this boot disk:
http://home.eunet.no/~pnordahl/ntpasswd/bootdisk.html
After doing this, consider treating your PC like your car:
Would you ever have one with only a single set of keys?
Create a second admin account for each of your OSs
and lock the passwords away in a safe place!

You can select which SAM file to deal with.

Thanks.
In a thread called Password below you advised:
"Control Panel / Users and Passwords / Untick the box that
requires users to enter a password"
Then the state of this box should be written somewhere inthe Registry, and
probably can be changed directly in the Registry from another w2k on this
computer - is this the case?

 

[Pegasus \(MVP\)]

This is correct but it is irrelevant for you. When you untick
that box then you're prompted for the correct password,
which is then encrypted and stored somewhere. If you
were to untick the box by a direct registry hack then Windows
would attempt to log you on automatically and fail because the
registered password does not match the required password.

There is no shortcut - you must reset your password!

Just for clarity sake, the password is not stored in the SAM
in an encrypted form. Rather a hash of the password is (or,
if practices are not followed to shut of storage of the LM
hash also, then two hashes are) stored.
Hashes are not uniquely reversible whereas encrypted
storage would be, hence the password is not deterministically
recoverable from the SAM storage.

First thing is unstick that capslock key, then Ctrl-Alt-Del and choose
