Well now that would be a neat trick. I hope not.

Quote: is there anyway for programmers to catch the password of login in WinXP when it starts up? The only way is to write a replacement GINA DLL. NT-based versions of Windows use GINA to respond to user logins. GINA is responsible for displaying the actual login prompt that the user sees. If you write your own GINA DLL, you can display your own login dialog, and thus have access to the credentials that the user types in.

It's too big a topic to cover here but i have written a series for the Borland Developers Journal that covers this - this last article will be out this month or next and covers exactly this i.e. password grabbing of winlogon password. It is possible to do this with a GINA stub without too much trouble, If you wish to pursue a private discussion about this (as it is a bit off topic) post back and I'll send you an e-mail.

Of course, if you know the administrator account password, you can change any account's password. So assuming no one knows the admin password: http://www.petri.co.il/forgot_administrator_password.htm -- Bruce Back to top ÈÇÈß Guest Posted: Tue Sep 19, 2006 1:05 pm    Post subject: Re: XP Login password and what happen if we dont know the admin pass??

The GINA only processes the logon attempt and then passes the credentials back to winlogon. It is at this point that the user details can be intercepted and process but this is reliant on a successful logon attempt - if you don't know the password and thus can't logon then this will not be any use. Also, you need to be able to gain access to the OS in initial the GINA installation I.e. copy it onto the harddisk and modify the registry - again this is going to be problematic. Not wanting to sound like a broken record (and defiantly off topic) but this is bad administration and management - no password no pay - that's what I say :-) If you don't have any success with the links provided you might consider looking at lophtcrack - i've had some very good success in the past with this but i'm not sure what the situation is with XP and 2k3. good luck...

It is also COM based as far as i can remember - i'm doing some work on it now (in between everything else) Mike C "Michel Leunen" <nospam (AT) noreply (DOT) please> wrote in message news:450ee62c$1 (AT) newsgroups (DOT) borland.com...

Right now, my program is undergoing some testing, so I thought I'd drop in and read some messages to spend my time. This topic raised a question with me: I have seen programs before that would automatically log a person in using the current user's information. If you are on an outside computer that is not part of the network, a login prompt displays that the user enters the same login name and password that the company computers use. How does the software login an individual for these cases? Does it store the user's password, or get the current user from the registry, or something different? I always thought that was a neat trick! Regards and Happy Winter! :) "ÈÇÈß" <babak_info (AT) Dont (DOT) spam> wrote in message news:450db877 (AT) newsgroups (DOT) borland.com...
