- Graphical Identification and Authentication DLL (GINA)
-
-
- The GINA sample demonstrates the Gina-related functions.
-
- To install the Gina DLL, copy it into %systemroot%\SYSTEM32, add
- a registry value of type REG_SZ named GinaDLL under the key
- \HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon,
- and reboot the machine.
-
- WARNING! - It is possible to make your machine unusable if you install a
- replacement Gina and it fails. To avoid this situation, be sure that you
- have a method of accessing the %systemroot%\SYSTEM32 directory independent
- of the Windows NT installation you are testing on.
-
- If the Gina sample malfunctions, and you are not able to log on to fix
- the problem, you can recover by doing one of the following:
-
- * If the test machine is on the network and you have an account on
- another machine with Administrative privileges on the test machine,
- open the test machine registry remotely with regedt32 and delete
- the GinaDLL value.
-
- * If the test machine is on the network, and %systemroot%\SYSTEM32 is
- available on a network share for that machine (e.g. \\<name>\c$),
- rename GINA.DLL to something else with a command like
-
- ren \\<name>\c$\winnt351\system32\gina.dll gina.sdk
-
- reboot the test machine, and delete the GinaDLL value from the registry.
-
- * If the test machine will dual boot to another version of Windows NT
- or another operating system capable of accessing %systemroot%\system32,
- boot to that operating system, delete %systemroot%\system32\GINA.DLL,
- reboot, and delete the GinaDLL value from the registry.
