I have a problem with one of my Samba users that I can't figure out. For some reason, his laptop continues to open and close sessions to the Samba server at the rate of about 5/sec even though he is already connected and viewing files. It all started yesterday morning and it got so bad that I had to kill his ethernet port by yesterday afternoon.

I have checked his machine for viruses and spyware, but didn't come up with anything so I'm wondering if something is misconfigured on the server or on his machine. Does anyone know what would cause this sort of behavior? I need to figure out something soon so I can get him back on the network without slowing down all my other users.
