Hi,
I was wondering if anyone knew of a way to detect other computers on a
network (running my program) if all connections were made via TCP. All
computers are running WinXP, but I'm limited to .Net 2.0. Any and all ideas
are welcome.
Thanks.

Usually one either registers ones programs with a central service, or uses
some kind of discovery algorithm. One very simple discovery algorith is a
broadcast on a known port.

Thanks for the idea, but I require a little clarification. How do I
broadcast over TCP? The TcpClient class takes an IP address for its
constructor; what should I use for that? Should I use the Socket class
instead?
I can't use a central service, due to the P2P nature of the network.

To start with the latter point: many p2p networks do use a central server.
Check e.g. http://en.wikipedia.org/wiki/Peer-to-peer

Of course "pure p2p" does not.

Re: discovery algorithms: Check e.g.
http://en.wikipedia.org/wiki/Service_discovery
as a starting point.

Iff your programs are all running on the same physical network (within a
network segment), you may be able to use a broadcast. This is an UDP
service - sorry, I forgot to distinguesh.
