Add this to the [global] section of the /etc/samba/smb.conf
netbios name = <hostname>
name resolve order = bcast host
Then either restart the smbd and nmbd services or reboot the system.
You should now be able to browse the network shares.
Question
I've been having this problem since around 12.04. I just did a fresh install of 13.10 with a dual boot of Windows 7 and the problem still exists.
Oops! Something went wrong.
Unhandled error message: Timeout was reached
If I wait about 10 seconds and press Browse Network again, it will work fine the second time in.
Any ideas on how to fix this issue?
