The "pnrpsvc" is a part of Microsoft Windows OS. It is a system and hidden file, located in the system folder and the usual size is around 269,824 bytes. The pnrpsvc.dll process is safe and disabling it can be risky, because programs on your computer need it to function properly.
An Overview of This "DLL" File
The acronym stands for Peer Name Resolution Protocol Service; it is a library of published name resolution protocols enabling internet hosts to distribute peer names and their corresponding IPv6 addresses and other data. Other hosts can then solve the peer name, establish peer-to-peer connections and retrieve the corresponding addresses and other data.
Peer Name Resolution Protocol service enables serverless peer-to-peer programs to communicate with each other across a network. HomeGroups and Remote Assistance are examples.
Peer names are composed of a qualifier and an authority. The authority is determined by a secure hash of an associated public key or if the peer name is unsecured by a place-holder. The qualifier is a string, enabling an authority to have several peer names for various services.
In case the peer name is secure, the publishing authority signs the PNRP name records, and can be confirmed with the use of its public key. The indiscreet peer names can be distributed by anyone, without the need to verify it. Several units can distribute the same peer name. For instance, if a peer is connected to a unit, any member of the group can publish the addresses for the peer name. The peer names are then resolved and published within a specific scope, which can be a site, the whole Internet or a local link.
