Chat programs for PC on LAN and Messenger for the office (free)

This is an article especially dedicated to office life, for those who need a private and secure chat tool that only works within a LAN.
So unlike traditional chats that work via internet connection, LAN Messenger programs connect only people who use a computer connected to the same LAN, to the same router, in wifi or via cable.
Although the use of chats like Whatsapp, Skype and Facebook have made these private and local chat programs less popular, they are still business tools that work independently of the internet connection (the important thing is the internal network, even if it does not come out on the internet) and that do not require access to social networks that can disturb work.
They are therefore programs that work on the Peer to Peer network, without a central server and with direct connection between the various users, even if the network is limited, as often happens in the offices of larger companies.
Below we find out which are the best "LAN Messenger" local chat programs via LAN for offices (or even at home if you have computers in different rooms), which are also free to use .
Contrary to what I thought finding free programs of this type it was more difficult than expected and even if they are not popular applications, the best LAN Messenger or Local Chat for offices are paid programs (which we are also going to mention).

File transfer can be done, a message history exists and there are options to customize.
Chats can be password protected.

LAN Messenger includes many other features such as file transfer, message recording and contact organization.
