I have written a custom password filter dll that I would like to deploy on a Windows 2003 domain (running in native mode). I place the dll in the system32 folder and then I edit the Notifications Packages value and add the name of my dll. I reboot the server but the Lsass.exe process does not incorporate my dll because I can still delete it after the reboot. What have I done wrong? For testing purposes I only deployed this dll to one of my domain controllers but I've made sure that in AD sites and servies that my subnet logs into that server.
