This DLL extends the standard GInA DLL from NT.
It mainly adds This DLL replaces the standard GInA DLL, executes, then points back to (executes) the original one.



Installation

The DLL must be copied onto the local hard disk and must be set up in the registry.

The key HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon of type REG_SZ must point to the absolute path of the file XGINA.DLL.

  2. Each Script value may be completed by a LogFile and / or a TimeOut value that overwrites the default one for this script only.

An example of a policy template file (XGINA.ADM) is provided.


Terminal Server Edition compatibility

XGina has been tested and is currently used on TSE (NT 4), but there is a little problem with the startup / shutdown scripts; as TSE launches a new Winlogon for each new logon, the scripts are no more called at startup / shutdown time but at each logon and X time at shutdown :-(
I hope to find the time to fix this asap (I need a semaphor that stays when the application stops, but that is not present at the next boot).
