Use Ophcrack or Offline NT Password Editor

Can you login as the local admin account and reset it?

If not you will have to do a preboot environment booting from CD and remove it that way.

I am running Ophcracker but it stop at Requesting events from the kernel.

I have used the offline NT password editor for years over different versions of windows. The only thing to be aware of on it, is if you have any kind of encrypted files, if you reset the password, it breaks the encryptioin to those files, so they are no longer accessable.

Use Hirens BootCD - Download | Hiren's BootCD PE

THEN SEE THE BELOW LINK

You could also use a bootable linux CD (like Ubuntu), and then use chntpw.

Although it seems quite shady that you have forgotten your password… I will agree with what others are saying and also say that offline NT Password Editor is the one to use. But use it via Hirens like BSOD’D has suggested.

Once you have created your bootable Hirens disc, boot from it and load the Offline NT Password utility and follow the information in BSOD’D’s second link.

If you follow it all correctly, it will work perfectly. - Just dont try to change a password with it, remove the password completely.

Why not use Microosft Dart? Microsoft Dart comes with the Password Lock Kit so you can reset passwords…

Reasons why Microsoft Dart is a bad answer to the specific situation (person facing the issue without a solution in hand):

reason 1) Microsoft Dart? Hadn’t heard of it… let’s look it up.

based on about 20 minutes of looking:

reason 2) Documentation. Not the lack thereof (there is plenty) but it seems to be written by someone who is far more verbose and writes far less directly than I do (and that’s pretty bad)

ex: from a document with an intended audience of IT administrators, the overview takes about a half page to say “it is a boot recovery cd. It can also be run from usb, the hard drive or PXE.” And after reading the overview, I’m still not 100% sure that is what it really means. It appears that you can pre-install it on the workstations, and their talking about both methods together without differentiation blurs the information.

Maybe I am particularly dense, but that whole overview says basically “Boot recovery CD; can also be run from USB, to hard disk or PXE servers.” And it doesn’t get much better as you go along.

reason 3) You have to build a different version for the specific os (i.e. W7 32 vs W7 64 vs WXP 32 vs server 2008 r2 32, etc. etc.)

reason 4) It isn’t entirely clear, but it appears that you need a different Dart version for different “levels” of windows (i.e. 2000/xp/2003 vs vista/2008 vs 7/2008 r2 vs 8/2012.

reason 5) Licensing: It appears that DART is part of MDOP. “MDOP is available as an additional subscription for Software Assurance customers.” I.e. It costs money. If you aren’t on SA, it would cost you A LOT of money.

Reasons why Ofline NT password editor (for example) is better at least for the question as posed:

  1. free

  2. quick: download, burn to cd and done. It is included on some multi-utility cds, or you can get it as a stand alone image.

  3. simple instructions, simple to use.

Reasons why Microsoft Dart would be good for planning for the problem above:

  1. it is good to be proactive

  2. it is from MS, so you would hope that it is more reliable than the other tools (though some of them are very reliable).

  3. IF you have SA and want to pay the extra cost for the Dart package, it does seem to have a number of other nifty tools. I have never had the need to use any of the other boot cds (hirens, linux) so, they may have similar nifty tools.

  4. the work needed to build the different images for different systems would not directly impact the repair of the problem as it would be done ahead of time.
