After you upgrade your computer to Windows Vista, custom Graphical Identification and Authentication (GINA) modules no longer work.

Graphical Identification and Authentication (GINA) Modules do not Work

Use one of the following procedures, as appropriate for your situation:

If you obtained the custom GINA module from a third-party software vendor or third-party hardware vendor, contact the vendor to inquire about a replacement. 
If you developed the custom GINA module, create a new solution that uses the credential provider model in Windows Vista. 
Note Custom GINA modules use the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GinaDLL
If the GinaDLL subkey is present, it contains the name of a GINA .dll file. The GinaDLL subkey is not present in default installations of Windows.
