If password protection is turned on, any user who has Administrator privileges can use the Users & Security command to see who is logged in. This can be done from any client.
The user list in Users & Security shows the machine name or IP address of any computers that are connected. The example above shows that two people are logged in—User Admin from a computer at IP address 192.168.1.14 and user Fred from a computer called GRANTB047/1.
