[Samba] Share disconnect after inactivity

[Andreas Schlager]

Hi list,

I've the strange problem, that after some time of inactivity a share is 
being disconnected. This leads to a red 'X' in the Workplace's list of 
connected drives. When opening a disconnected drive, the drive is being 
reconnected.

BUT: This has a very fatal side-effect: When f.e. an MS-Access database 
is open and the user does not use this db, the share is also being 
disconnected. The connection is not restored, when the user works again 
in the access-db.

My question: Is this a windows-behaviour or is this from the samba? The 
disconnected drives (marked with the red 'X') I can see also on machines 
connected to a Windows PDC, but no problems with access occurs there.

Many thanks in advance!
