Try Pidgin; as far as I know it's the go-to open source option.

It supports both server-based messaging as well as the serverless Bonjour protocol, so if you don't need or want to set up an IM server, Pidgin will still work.

In our company we use OpenFire, it's opensource works fine.

This is only a solution if you're a network administrator and it's a company or department wide solution you need.
