Windows Vista P2P engine causes concern

Windows Vista comes equipped with its own, under-the-hood P2P networking system, it has emerged. The code’s presence was detected after a number of beta testers spotted unexpected levels of network traffic coming in and out of machines loaded with the preview code Microsoft released last month.

The P2P sub-system uses Microsoft’s Peer Name Resolution Protocol (PNRP) and is used to link machines in much the same way applications like Limewire, BitTorrent and the various instant messaging programs do. The software giant’s goal is the ability to provision network services without the need for a server.
