tl;dr Shared files are accessible, but server isn't visible in Windows listing.
I've got printers and some directories shared via Samba, but they do not appear in the listing when a Windows user opens their "Network". They can type "\computername\" and hit enter to see the shared printers and directories, but I'd like to make it easy to see the server listed along with other icons in their Network panel.
This used to work (ubuntu 13-something, I think), but recently (ubuntu 15.04) it doesn't. So something must have changed with the default configuration. It's probably a simple setting in smb.conf, I just don't know where to look. Any hints?
