Set PNRP cloud to resolve only

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.
