[ubuntu] I cannot access my NAS anymore

view story

http://ubuntuforums.org – I have a Synology NAS with a "Windows" share configured. When I click "Browse Network" => "Windows Network" in Nautilus, all I get is: "Unable to mount location Failed to retrieve share list from server " Note: This has worked 100% fine before, and I HAVEN'T CHANGED ANYTHING. Any ideas? (Hardware)
