[Win XP] changed pc from domain to workgroup and cant login

Ok so iv screwed up.

I changed a laptop from a domain to a workgroup and now cannot login

Now i know if i took the laptop to the old network and reconnected there i could log in.

Trouble is the network/business no longer exists!!

I dont know the local administrator logon either.

Does anyone have any suggestions other than wiping it.

Reason for not wiping it:

The laptop has a piece of software installed on it i need and i do not have the installation file/disks

alternative solution would be to somhow rip the software out of the machine and install it on the new formatted os. But i dont think this is possible :confused

Any suggestions or help would be much appreciated.

 

Hi

You could use either of these to reset the local admin password:

http://ophcrack.sourceforge.net/

http://pogostick.net/~pnh/ntpasswd/

 

Thankyou for such a fast reply.

I have tried the NTISO you suggested but it seems not to work for me :/

I am going to try the other piece of software and see if this works.

another thought crossed my mind. Is there anyway to do a system restore on XP whilst being locked out?

 

Thankyou for the fast reply

Already tried ntpasswd software with no joy. I will give the other piece of software ago.

Thankyou again

 

Seems ophcrack does not work either.

Starting to panic abit here.

Is there anyway of getting a system restore to work??

 

I don't think you can do system restore without having access to an account.

However, there's another method listed here (and a link to buy software that apparently works as well). Scroll down for the free instructions part:

Tgell recommends Trinity Rescue Kit using the WinPass software to reset the admin account to default. http://trinityhome.org/Home/index.p...D_372_FROM_GARR&front_id=12&lang=en&locale=en

Did NtPassword and Ophcrack act like they were changing the password but you were still unable to get in afterwards? (I've only used NT password so I can't say how Ophcrack works.)

 

I have always had good luck with hiren's boot cd. It has a ton of different tools on it. Including password resetting tools.

I think they are up to HBCD 14 now. It is totally free and its nothing but open source, share ware and free ware programs.

Hope this helps

 

Should sach2's suggestion not work, you could try this. http://www.makeuseof.com/tag/konboot-computer-prank-passwordbypass-tool/. I've used it successfully when NT offline password disk wouldn't work.

 

Hi Sach2 thanks for your reply, Yes that is exactly what happened. However when the programs list the username none of them give [ADMIN] next to anyof the accounts. Promoting an account to admin does not change this.
