SMB disconnect

[tomeks11]

I have a problem disconnecting Winows from Samba.
When I detach a samba resource under Widows and it is not used for about an hour, the resource disconnects. The Explorer window closes by itself. I checked communication in WireShark.
I have similar logs with the Samba resource in Debian but this problem does not occur.
