What does the NetSessionEnum function achieve in the context of NetAPI polling?

The NetSessionEnum function is used in the context of NetAPI polling to retrieve information about active network sessions connected to a server, typically within a Windows environment. Specifically, it provides details about user sessions, including their connection status. Therefore, it is instrumental in tracking user logouts because when a session is no longer active, the function can identify this change.

The function does not handle user authentication directly; it simply enumerates existing sessions, meaning it will provide data on who is connected, their session state, and related details. Similarly, managing firewall policies or encrypting session data are not functions associated with NetSessionEnum. This function focuses primarily on obtaining session information, making it capable of identifying when users disconnect or log out from the network.
