This is IPv6 stuff.

You have either installed IPv6 manually,
or it was installed as part of the Peer-to-Peer
components from the Advanced Networking Pack:
http://support.microsoft.com/?kbid=817778

Check in Add/Remove software, WIndows Components, Networking.
If Peer-To-Peer is selected, then that's where it came from.

The 3 tunnel adapters are virtual network cards used to
provide IPv6 connectivity in different ways over the
conventional IPv4 Internet.

If you'd like to learn more, start here:
http://www.microsoft.com/windowsserver2003/technologies/ipv6/default.mspx

For an explanation of the various tunneling technologies, follow the
link to IPv6/IPv4 Coexistence and Migration.

You can un-select it if you wish, and un-instal IPv6
from the Network Properties of your network card.

Personally, I'd un-install IPv6 unless I had IPv6 routing working.

The reason I say this is because it's possible you might try to visit a site
which supports both IPv4 and IPv6. When you browse to the site, DNS
resolution will return both IPv4 (A) and IPv6 (AAAA) records. By default,
the IPv6 is preferred, and the site is contacted over IPv6. However, if
your IPv6 enabled box can't actually route IPv6 anywhere, this will fail.
And it will take a long time to time out before falling back on IPv4.

( I discovered this when my IPv6 tunnel from my IPv6 router to my ISP's IPv6
tunnel endpoint got broken by a misconfigured firewall. )

Great info, Ron. Does IPv6 have anything to do with IPSec options on a connection's Advanced TCP/IP Settings tab?

No, IPv6 is a new protocol.
The IPSEC options in the TCP/IP ( IPv4 ) settings are IPSecurity.

There's nothing in the TCP/IP ( IPv4 ) properties which are anything to do
with IPv6.
