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

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.

Yes, as remy has pointed out the GINA is responsible for the interactive 
logon process and password arbitration. 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.  Alternatively subscribe to 
BCB journal and read away.

Hi
someone put a password on her computer at work
and she leaves the work without telling us that word !!!
Now we need to use the PC, its also OK to have not the login form, we can
change the Windows by format , etc... but we want to not change the OS and
all those settings.

Thanks

Yes but you must be aware that with Vista the GINA dll will no longer 
exist, "the user will not be able to successfully install custom logon 
applications" according to msdn:

Of course, if you know the administrator account password, you can 
change any account's password. So assuming no one knows the admin 
password:

and what happen if we dont know the admin pass??

Did you look at the link that Bruce gave you for that?

Presumably not all of it ...

Yeh in this case, no gina is going to help you.  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...

Just as a little point of note - vista does provide a mechanism for 
interacting with the logon process - it's just not a GINA per-say - the 
system is more akined to the network notification packages that currently 
exists on 32-bit Win NT based system.  It is also COM based as far as i can 
remember - i'm doing some work on it now (in between everything else)

Hi All,

Haven't been around in a while. Been developing for a PocketPC using 
eMbedded VC 4.0.  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! :)
