Description:  

This policy setting limits a node to resolving, but not publishing, names in a specific Peer Name Resolution
Protocol (PNRP) cloud.

This policy setting forces computers to act as clients in peer-to-peer (P2P) scenarios. For example, a client
computer can detect other computers to initiate chat sessions, but other computers cannot detect that client
and initiate sessions with it.

If you enable this policy setting, this computer cannot register PNRP names, and cannot help other computers
perform PNRP lookups.

If you disable or do not configure this policy setting, this computer can publish PNRP names and help other
computers perform PNRP lookups.

Supported on: At least Windows XP Professional with SP2.
