The command that shows the username and IP address used to access the system via a remote login session is "Net sessions." This command provides information about the users who are currently connected to the system, including their usernames, IP addresses, and the number of files they have open on the server. It is particularly useful for monitoring remote access to a system and for identifying active sessions, which can aid in forensic investigations.

In contrast, the other commands serve different purposes. One of those commands is used to display information about shared files or resources on the system. Another one focuses on the file handles that are opened and the users who have them open, while the configuration command provides various settings and configurations for the system but does not focus on user sessions. Therefore, when needing to track remote login activity specifically, "Net sessions" is the most relevant command.
