Notification Packages


Data type


Default value


File name [ file name ...]



Specifies the dynamic-link libraries (DLLs) that are loaded or called when passwords are set or changed. To specify more than one file, list the file names one above the other by pressing ENTER between each file name.

This entry is often used to load libraries for services such as File and Print Services for NetWare.

You can use this entry to implement custom DLLs that specify alternate criteria for valid passwords, such as complex password rules. Notification packages that implement password verification are recommended for all primary and backup domain controllers. You can also write a custom password filter to fulfill special security requirements.
