This service pack 3 of Windows XP contains “version 2 of the Peer Name Resolution Protocol (PNRP) which is compatible with Windows Vista and Windows Server 2008. PNRP v2.0 was available as a separate download for XP SP2, but now it comes directly with the service pack,” informed a member of the Microsoft Peer-to-Peer Networking.
This means that with SP3, XP users will be able to enjoy the scalability and boosted performance in terms of network bandwidth usage just as those of Vista SP1 and Windows Server 2008. Version 2.0 of PNRP was one of the enhancements introduced for the peer-to-peer networking capabilities of Vista RTM. Version 2.0 is also up for grabs for Windows XP as an update, and only PNRP 2.1 is included in Windows XP SP3, according to the official documentation for the service pack.
“The Microsoft Windows Peer-to-Peer Networking platform [offers] the Peer Name Resolution Protocol (PNRP), a secure, scalable, and dynamic name registration and name resolution protocol first developed for Windows XP and then upgraded in Windows Vista. A PNRP resolution includes an address, port, and possibly an extended payload. The system is fault tolerant and there are no bottlenecks,” revealed Microsoft.
