I have a USB RFID reader that just reads the 10 character cope and then dumps it as text into the active application as it uses USB-HID drivers to make it appear to be a keyboard. I have looked at your RFIDpoll.dll source but I'm just no good with programming. Would it be possible to create a DLL that just has a small input box in which the RFID code would be dumped and then it uses the pollgina and reg keys generated by RFIDAuth.exe to login? If so could you tell me what Phidgets code to strip from the DLL source?

Thanks, great projects!

Hmm, I'm using Windows XP SP2 and it's working fine for me. The only other thing I can think of is the Phidgets library... have you checked into the various posts on this forum about how horribly wrong the Phidgets library has gone through the update process? Also be sure to read the UPDATE sections in the posts in the download section of the forum. The short version is, the Phidgets library is not backward compatible so projects like the GINA DLL files that are compiled with one version of the library will not work with any other library version. I'm not sure if this is the issue because your post indicated that the reader does work and account data and passwords are put into the logon screen, it's just that winlogon crashes afterward. But, it's worth a shot.

Also, the only other thing I can think of is that your system may have a virus or malware of some sort or even a keylogger that is somehow interfering with the logon process and causing the crash. The GINA DLL is a finicky piece of software and it is really meant as a guide for someone wanting to impliment a more "production" quality solution.

Hi Amal,

Unfortunately eliminating the Change Password dialog didn't solve the problem.  The code is still causing Winlogon to crash here.  I've applied all of the Windows Update patches to my system which is running Windows XP Professional SP2.  Any other options?  Does it work OK for yourself with the same OS/SP combination?

Thanks, Dan

ok cool, thanks for clearing those points up. eagerly awaiting confirmation of change password dialog test ;)

To answer your questions

    - Regular 32 bit windows

    - No other GINA replacements loaded

My guess is the change password dialog - so let me get rid of that and see if it fixes the problem, I'll report back later.

Thanks for the exceptionally quick reply.

Hi Dan,

You may be correct that the GINA project does not properly account for the "change password" dialog. By chance do you have any other security products loaded like the U.are.U fingerprint scanner or something similar? These types of products that modify the GINA login process will most certainly cause problems with the GINA project.

Lastly, I know this is probably not the case, but you don't happen to be running Windows XP Pro 64 bit edition? The GINA project is 32 bit only.
