Windows logon password cracking


d3v

Recommended Posts

Hi all,

Customer can't remember his Windows logon password and so I booted to UltimateBootCD and selected Offline NT Password Editor and went through all the steps blanking all the user accounts as well as activating the disable Administrator account, rebooted, selected a user account, left password field blank, hit enter and got a "Password incorrect" messege. WHAT?

So I tried Offline NT password editor but this time I actually set passwords for all the accounts, tried again but the same DAMM deny messege appears on WIndows logon screen!

I hate it when this stuff dosn't work :(

Plz help!

OS is Vista Home premium

Don't know about other systems. But in XP, in safe mode, admin account is visible. So did you try it?

BTW Hiren's BootCD has many other tools for it. ;)

I actually did try Hirens NTPWD tool, which did not work, either. DK27 I managed to activate the Admin account in Offline NT password program, and now the Admin account appears alongside the customers acount, but again no amount of password changing or blanking works!

I'm tempted to reformat cos it dosn't look like they have ever used the laptop before, so theres nowt to backup, and it gets rid of all the factory loaded crapware at the same time!

Nah but seriously, I'd prefer to just crack existing password or write a new one. I'll have another go later tonight!

cheers.

EDIT: He just phoned me remembering the password. Well it worked, I'm spirsed it did after all the edits I did to the SAM file in those (useless) password cracking programs.

I might as well do some tweaking/optimization while I have his laptop here now.

Cheers all.

I would have recommended the same, but doubt it'll be be good for Vista...

There is I believe tool called Ophcrack LiveCD - does the job!

yes ERD commander is great way but in my opinion u should use theOphcrack live cd with ophcrack u can able to see all the guest,admin and limited user accounts and passoword also if u hav vmware installed on ur system u can also see those Vmware account usernames and passwords rtoo in text format

You can dnld it from ophcrack =sourceforge =net dont forget to chose which cd u need there r diffrent for xp and vista users

Not sure if it works on Vista but the Geek Squad mri 5.1.1 does remove login passwords.

Did you have to add the 'Tables'.. or is all of it ready to go and burn as is? Just wondering.. I haven't ever used this or heard of it until you mentioned it earlier in the thread...

If you're referring to the Spotmau PowerSuite 2010, the table of contents should have:-

01.) A BootCD in .iso format with a burning agent

02.) The 'setup with a serial' for those who would like to install the Suite on their system.

LOL.. No I was referring to the other CD the Orphcrack CD.. There are tables and they are any were from a few hundred MB to 10GB in size for XP and Vista..

But yes you are right.. and I have always had better success installing the software.. even when using the BootCD.. I believe some elements may actually depend on the Program Files Folder being in tact and on the drive.. I installed mine on 7 right after this the other day..LOL.
