Way for software to discover others on the network?

I am developing a system where multiple client apps are going to communicate with a server app. I will probably use TCPIP classes to facilitate the communication.

However, is there a way that a client install can automatically discover the location of the server software on another machine?

Thanks

UDP is a great way to do discovery on networks. UDP supports broadcasting, which will send out the message to the entire network (or some specific subnet) and then if someone is lisetening, they can respond to the broadcast, giving you a list of servers available.
