i have seen chat program code (client/server) to be
implemented across the Internet using Java.But for that we need the
server to be www.mychat.com. What i want to know is that can
we write a similar chat prog in Java and implement it on
a LAN running Win NT? If so, what would the code be like?

Hm, interesting number of points for this type of question...

In your case you have to write the communication between the client and the server using sockets. First, I hope your LAN ahs IPs assigned to each machine.
The server listens to a particular socket on the NT machine. The client contacts this socket and announces himself to the server program. Then, you have to define some simple messaging protocol, in order to be able to implement the chat sessions.

The Web chats are something else. They use the HTTP layer to transport their messages and since the connection there is stateless, the chat server CGI program must have a way to distinguish the different chat clients, which the do through cookies in the browser or some other way.

Cheers,
