This kick-off screencast introduces you to the foundation of Peer-to-Peer applications, PNRP. Peer Name Resolution Protocol is the the underlying mechanism used by applications to discover peers on a network. This can either be a local subnet or the Internet at large. One of the great things about PRNP is that is even works across NAT devices.

In this screencast, I introduce you some fundamental PNRP concepts and show how you can use the command line to test out the basics. This screencast is not intended to be a deep dive technical exploration. Rather, it lays a sufficient foundation for you to understand what is going on in future screencasts and lets you get started building P2P applications as soon as possible.

Damn - only local resolution/registration is working. Not global. Any hints?

what is the state of the Global cloud? netsh p2p pnrp cloud show list? Also, take a look at netsh interface teredo show state and see what it says. Client firewall blocking things? Lots of places to start looking unfortuantely.

I think the Cloud thing only works with IPV6. Correct me if i am wrong.
