I have installed winbind and libnss-winbind as usual for NetBIOS name resolution on Ubuntu Gnome 17.04. This works fine and I can get a response pinging by a random host name on the local network.
Up on reboot however winbind stops resolving NetBIOS names. I can see from
systemctl status winbind that the service is active and running, and ready to serve connections. Restarting the service fixes the issue but it's broken again on reboot.
Looking at the log doesn't really give any further information.
Any help appreciated.
