When using the 'net use' command to connect to a remote host with the syntax \192.168.44.213, the local logon credentials are sent to the specified IP address to establish a connection. This typically involves sending the username and password currently logged in on the local machine to authenticate with the remote host. Other options, such as granting guest user account permissions, returning a list of running processes, or exchanging a temporary authentication key, do not accurately describe the default action of this command.
