I have the very same problem - Recently unable to browse the network via Nautilus -> Places -> Network -> Windows Network, but making a direct connection using Samba worked. When attempting to browse the network, I get the same error as OP. I just installed new updates on the morning of Friday July 16. I don't remember which updates were applied, and I am not sure how I can verify which updates were last applied. However, I have run the /usr/lib/gvfs/gvfsd -r command in Terminal. It seemed like nothing was happening in the Terminal window, and I let it run while I attempted to browse the network via Nautilus -> Places -> Network -> Windows Network. While attempting to connect to Windows shares, this is what was dumped in the Terminal window: ### SMB-BROWSE: g_vfs_backend_smb_browse_class_init - default workgroup = '(null)' lp_load_ex: refreshing parameters Initialising global parameters params.c:OpenConfFile() - Unable to open configuration file "/home/amanderge/.smb/smb.conf": No such file or directory pm_process() returned No lp_load_ex: refreshing parameters params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf" Processing section "[global]" doing parameter workgroup = WORKGROUP doing parameter server string = %h server (Samba, Ubuntu) doing parameter dns proxy = no doing parameter log file = /var/log/samba/log.%m doing parameter max log size = 1000 doing parameter syslog = 0 doing parameter panic action = /usr/share/samba/panic-action %d doing parameter encrypt passwords = true doing parameter passdb backend = tdbsam doing parameter obey pam restrictions = yes doing parameter unix password sync = yes doing parameter passwd program = /usr/bin/passwd %u doing parameter passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . doing parameter pam password change = yes doing parameter map to guest = bad user doing parameter usershare allow guests = yes pm_process() returned Yes lp_load_ex: refreshing parameters params.c:OpenConfFile() - Unable to open configuration file "/home/amanderge/.smb/smb.conf.append": No such file or directory pm_process() returned No added interface wlan0 ip=fe80::214:a4ff:fe12:67c2%wlan0 bcast=fe80::ffff:ffff:ffff:ffff%wlan0 netmask=ffff:ffff:ffff:ffff:: added interface wlan0 ip=10.10.10.101 bcast=10.10.11.255 netmask=255.255.252.0 Using netbios name AMANDERGE-LAPTOP.
