Vista Network Device "tunnel" adapters and IPV6

[ikonia]

I've just put a Windows Vista machine onto my network.

in the network properties options for the network card I uncked the "IPV6" options.

If I view the network status I see

"IPV4 Local connection
IPV6 Limited"

Why is IPV6 limited connection ?? I've disabled it, it should be "no connection"

I've also noted (this machine has 1 physical nic in it with 1 IP address) the if I do an "ipconfig" I see the following details.

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : no-dns.co.uk
IPv4 Address. . . . . . . . . . . : 10.11.216.6
Subnet Mask . . . . . . . . . . . : 255.255.255.192
Default Gateway . . . . . . . . . : 10.11.216.1

Tunnel adapter Local Area Connection* 6:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

Tunnel adapter Local Area Connection* 7:

Connection-specific DNS Suffix . : no-dns.co.uk
Link-local IPv6 Address . . . . . : fe80::5efe:10.11.216.6%10
Default Gateway . . . . . . . . . :

Tunnel adapter Local Area Connection* 9:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

What the heck are these "tunnel adapters" ??? and why is adapter 7 not showing as media disconnected. I have no private networking/vpn/sharing/crap setup, just one box, one card, one static IP on cable.

Where native IPv6 to IPv6 connections aren't available, I believe IPv6 is still tunneled over IPv4.

You have only disabled IPv6 on that one particular interface. To completely disable IPv6, you will also need to disable it on the loopback interface plus any tunnel interfaces.

See this Microsoft article for more information on disabling IPv6:

Hope that helps.

I have tried all that - it doesn't seem to connect at all - even when I disable everything as denoted in the error message 'an error occured while releasing interface Loopback Pseudo - Interface 1 - The system cannot find the file specified.
The operation faled as no adaptor is in the state permissible for the operation

What do I do now?

It would be straightforward if it wasn't Vista!
