Currently we are using Google Talk as messenger at our work place. Now we are supposed to replace it with some LAN based messenger. It should have at least following features chatting ( if logs are stored some where than it is good ), File sharing. Thanks.
you could run openfire
- it uses jabber (the same protocol as gtalk) so your learning curve is minimal - its free, with the option of support (with some paid plugins) and fairly simple to set up and run. management is through a web interface. Its free and open source as well, and runs on windows or linux
Pidgen ZeroConf using the Bonjour protocol no server to setup, the users can see each other as they come online via brodcast Link explain installation on Windows/Linux/Mac
Using it for the better half of the year, works_as_expected = true;
Update: you don't have to : "Use the SAME 'Hostname' for ALL clients" as the guid explains
I can only recommend LANTalk.NET, it is not free but shareware, you can try before you buy.

You can have a look at answers to my related question:
I have used Borgchat mostly because of its Multilanguage support and easy access to other Computers shared folders.
I would recommend Teamtalk. Teamtalk offers Chat, File Sharing & Remote Desktop all in one tool. Also, it works with both Windows & Mac.
