Description:  

This setting sets the seed server for the global 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.

Any node running peer to peer can be used as a seed server. No configuration is needed for the seed server
itself.

This setting provides the added flexibility of allowing your users to use their peer-to-peer applications at
home as well. Here are the four ways in which you can use this setting to control the seed server used in
your corporation.

1. In order to use the global, well known seed server on the Internet only; enable the setting, leave the
seed server list empty, leave the checkbox unchecked.

2. In order to use a corporate seed server only, enable the setting; insert the fully qualified domain name or
IPv6 address of the corporate seed server; and check the checkbox. Using the corporate seed server only
will prevent your mobile users from being able to use their peer to peer applications at home.

3. In order to use a corporate seed server and the global seed server, enable the setting; insert the fully
qualified domain name or IPv6 address of the corporate seed server, leave the checkbox unchecked. This is
the setting which will allow your mobile users to use peer to peer applications at both work and home
seamlessly.

4. In order to not use any seed server, enable the setting; do not insert a seed server name; and check the
check box.

If this setting is disabled or not configured, the protocol will revert to using a public registry key to determine
the seed server to bootstrap from.

Supported on: At least Windows XP Professional with SP2.
