[tab name=’Windows XP Pro x64′]
Windows XP Pro x64
Default Description
Enables Serverless Peer Name Resolution over the Internet.
Additional Information
This service is unavailable until the installation of Service Pack 2. This service does not install by default after the installation of Service Pack 2, but if needed, you may install it later by heading to under Control Panel > Add or Remove Programs > Add/Remove Windows Components > Select “Networking Services” > Details button > Check “Peer to Peer”. This service seems to have something to do with IPv6 and functionality that has not been fully implemented. Microsoft tends to throw in services in older OS’s that may be used at a later date to speed adoption. Leave this not installed for now.

It has been reported to me that Verizon FIOS Internet service needs this to remain connected. However, I cannot verify this fact as I do not have FIOS.
