Local Password Cracking

I have some dell OptiPlex 380 desktops that need to be removed and rejoined to the domain as they are out of sync.

I used Ophcrack to get to the local passwords but it has these accounts, Administrator,Temp, Guest.

They are all disabled so I still can log into the machines. Is there a tool to re enable these accounts? Is there a tools to make a new account?

Any other methods would be welocome. Trying to avoid a wipe and reinstall of all these desktops OS and apps as they are all unique. No golden image to use here.

OS is windows 7

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Google nordahl and boot disk. That one can reset and enable. The tool calls enabling unlocking.

That's Petter Nordahl-Hagen's website.

The procedure below won't use any "hacks" of the Windows security database and uses the normal Windows tools to change the account.

Procedure:
Start de desktop via the Windows 7 DVD
Press Shift-F10 to open a command prompt window
Execute:
cd /d C:\Windows\system32
ren sethc.exe sethc.org
copy /v cmd.exe sethc.exe
wpeutil reboot

Open in new window

Start Windows 7 normally
Wait until the Windows 7 logon screen appears
Press 5 times the shift key (quickly after eachother)

A command prompt will start under the SYSTEM account.
You can now activate the account and also change the password.
net user Administrator /active:yes
net user Administrator <password>
exit

Open in new window

From the command prompt you can even start a "mmc.exe", load the "Local Users and Groups" snap-in and do it via the GUI.

Change back the renamed sethc.exe by:
Start de desktop via the Windows 7 DVD
Press Shift-F10 to open a command prompt window
Execute:
cd /d C:\Windows\system32
del sethc.exe
ren sethc.org sethc.exe
wpeutil reboot

Open in new window

Start Windows 7 normally
Logon with the Administrator account and (new) password.

Use the utility (Offline Windows Password & Registry Editor) that Darr provided a link to. It's not too hard to figure out, and is very useful in many instances. You would be able to reenable the accounts, and even reset the passwords if you'd like. (Obviously you can also do registry edits if you ever needed to, but I haven't had to use that side of it)

Just download the files so you can make your bootable CD/DVD or flash drive. I've never had any problems with it. When you're exiting, just don't forget to let the program write back to your hard drive (save the changes you made to accounts).
