from: http://askubuntu.com/questions/339702/network-service-discovery-disabled-what-does-this-mean-for-me

- Network service discovery disabled: What does this mean for me?
Every time at boot I get a message “Network service discovery disabled. Your current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled.”

A-1.

It looks like avahi-daemon is started when the network connection is established
(/etc/network/if-up.d/avahi-daemon). This notification is informing you that
mDNS (Avahi) has been disabled. It's only used for a small number of
applications that only work on the local network, it won't adversely affect your
internet connection or DNS.  The most well known use for mDNS is sharing music
with Rhythmbox (or iTunes) over your LAN. It's an Apple technology, but it's
largely been ignored in favour of uPNP or DLNA.

To disable it, you must edit the file /etc/default/avahi-daemon as root:

sudo -i
gedit /etc/default/avahi-daemon

and add this line (or change it if already exists to):
AVAHI_DAEMON_DETECT_LOCAL=0

A-2.
According to the Avahi wiki there are two workarounds:
In /etc/avahi/avahi-daemon.conf uncomment and change the line with domain name to
domain-name=.alocal
Second one:
In /etc/nsswitch.conf delete a [NOTFOUND=return] text.
