NPS agent technology

The 'NPS agent' is an extension DLL registered in the 'Network Policy Server' service.

This DLL is called every time a user needs to be authenticated by NPS (RADIUS authentication) and when a session is opened and closed (RADIUS accounting technology). You will find more information on this technology in the following page of the MSDN:

Please note

  • NPS supports multiple administration DLLs. You shouldn't encounter any conflict if NPS administration DLLs are already installed.
  • The registry supports multiple DLL locations (REG_MULTI_SZ value type).
  • NPS calls the functions in the DLLs in the order in which the DLLs are listed in the registry.
