disconnected network drive - network drives.gif (0/1)

have a small network with three stations

i have noticed that when any one of the systems is booted the network
drives are all marked "network drive" in windows explorer

after the system has been up awhile they are marker "disconnected
network drive" clicking on any one of them changes the status to
"network drive"

i would assume that what is happening is the are reconnected at logon
and due to inactivity disconnect to save resources

is there a way to not have them time out and disconnect?

thanks
