Computer Configuration\Administrative Templates\Network\Microsoft Peer-to-Peer Networking Services\Peer Name Resolution Protocol\Site-Local Clouds Description
This setting sets the seed server for the site local cloud to a specified node in the enterprise. The Peer Name Resolution Protocol (PNRP) allows for distributed resolution of a name to an IPV6 address and port number. The protocol, in some cases, requires a seed server from which to get bootstrapped. This setting allows for setting the seed server to a specified node in an enterprise. To use this setting, click Enable, and then enter a semicolon-delimited list of DNS names or IPV6 addresses in the available field. If you enable this setting and you don’t enter any address, no seed server will be used. If this setting is not configured, the protocol will revert to using a public registry key to determine the seed server to bootstrap from.
