There are Windows client event IDs 30808, showing that the connection to the network share is re-established (oddly, there is usually not an event showing that the connection is lost). The clients also show their mapped network drives as disconnected with a red X icon, but they immediately reconnect upon accessing them. I have tried setting smbclient configs with keepconn, sessiontimeout, and extendedsessiontimeout values raised, but it didn't resolve the issue. The server does not appear to have lost network connectivity, but I'll need to try and see if I can verify that 100%. Is there an option in the config file I might need to reconfigure?

It sounds like this is a Windows problem then, but that smb.conf was awful.
