Loading And Running A GINA DLL

Windows NT is shipped to load and execute the standard Microsoft GINA (MSGINA.DLL). To load an alternative GINA, you must alter the following registry key value:

Key Name: \HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Value Name: GinaDLL

Value Type: [REG_SZ]

If this key value is present and non-null, then it should have a GINA DLL name. Winlogon will load and use that GINA DLL.
