Users and server show connected twice

Again, I am an NT Tech supporting a small Novell network. I have one server, yet using monitor>Connections on the console, the server shows connected twice, and now 3 times with a * in front of the server name. What does this mean and can it be causing any problems?

Secondly when a user logs on he also shows up twice, once with an * in front of his user name and once without. What does this mean?
