[Samba] Slow listing of mapped drives in Explorer

[Dennis McLeod]

Perhaps on your Windows clients, set the Autodiscconect to -1 (never
disconnect)

At a command prompt type:
"net config server" to see the current setting.
15 minutes is the default

To set it to never disconnect:
"net config server /autodisconnect:-1"
