I found this FAQ that I posted below. Is there a way I can check what the current setting is for the time when connections are dropped? I know how to set it, but I want to check it.
Why some mapped network drives show a red x
SYMPTOMS: You find that the network drive mapping may be disconnected after 15 minutes of inactivity and Windows Explorer may display a red "X" on the icon of the mapped drive. However, if you double-click it reconnects quickly.
RESOLUTION: by default, idle connections will be dropped after 15 minutes. To modify idle time, at a command prompt using net config server /autodisconnect: minutes. For example, to set the Autodisconnect value to 30 minutes, you would run the following command line: net config server /autodisconnect:30. If you would like to turn Autodisconnect off, do net config server /autodisconnect:-1.
