In Ubuntu 13.10 (everything is up-to-date) I get randomly this error popup message, during working with shared folders using a VPN connection over the internet:
Unhandled error message: Failed to mount Windows share: Connection timed out
Effect: Working with shared folders is not working anymore / sometimes it works.
I was getting "Failed to mount windows share: Connection timed out" when trying to connect from an Ubuntu guest (in VMWare) to Windows 7 host (the physical machine). I could ping the machine, but not reach the shared folder. I changed the vmware network settings from 'bridged' to 'host only' (didn't work) and then to 'nat' and that worked. Each time you change these settings Ubuntu sees a network disconnect and then re-connect, and I suppose it is assigned a new IP address in the process.
