Services Utility: Peer Networking Group Authentication Service

Display Name (?): Peer Networking Group Authentication
Short Name (?): p2pgasvc
Executable (?): svchost.exe
Library (?): p2pgasvc.dll
Depends On (?): Peer Networking Identity Manager
Supports (?): Peer Networking Identity Manager, Peer Networking
Description (?): Provides Network Authentication for Peer Group Members.
OS (?): XP Home/Professional, Vista Home/Business, Server 2003, Vista Server
Startup (?):

Explanation (?):

The peer networking group authentication service provides Windows with the ability to authenticate peers in TCP/IP version 6 (IPv6). I imagine this allows an IPv6 computer to properly test the trust and integrity of seed servers and various peers. If you don't need this service then you don't need IPv6 and you can remove it from add / remove programs in the control panel.
