Changing Guest anonymous name

This is dealing with connecting to an unattended device. 

Is there a way to show who's logged into the computer instead of "Guest?" Instead of seeing 'Guest' is connected to 'Guest' can you make to where 'username or person logged in' is connected to 'name of the device'. It makes it difficult as an admin to know who is exactly connect to an unattended device. I've attached a picture for reference.
