The nadpwdext.dll file is a piece of the Password Power Authentication Plug-in for Notes (APN) from Pistolstar, Inc. This plug-in for Lotus Notes allows users to access the program through their Microsoft Active Directory password, meaning that they only have to remember one password. This can provide a more secure desktop in a work environment, and reduce calls to IT to reset passwords.
If you are seeing this dynamic link library file in an error you may have trouble accessing Lotus Notes. A reinstallation of APN may fix the issue, but you should first try cleaning your registry.
The registry is a database that works as an information desk for Windows. Every file installed on your system has an entry in the registry that tells Windows where the file lives on your computer and how to use it with which programs. If there is a mistake in a registry entry, Windows won’t be able to use the file and any programs that rely on it will break.
