NuWinC (NuFW Windows Client) provides NuFW authentication for Microsoft Windows 95/98/NT/2000/XP/2003/Vista. This software is available from INL. NuWinC can provide, when installed on machines of a Windows domain, a 100% transparent behaviour, meaning users will not even notice it starting or running. For more information about NuWinC, see http://www.inl.fr/NuWINc,68.html.
