Windows 7, how to delete ipv6 interfaces?

[ToddBooth]

I'm running Windows 7, 32 bit, Professional.  Consider my following commands (administrator cmd prompt):

netsh interface ipv6>show interface

netsh interface ipv6>delete interface 23
Catastrophic failure


netsh interface ipv6>delete interface 17
Catastrophic failure


Does anyone know how to delete my numerous and duplicate ipv6 "Local Area Connection" interfaces?

Thanks,

Have you tried just resetting the whole thing?  Try a netsh int ipv6 reset

[ToddBooth]

I found one solution!!!

My solution follows.  Perhaps there is a better solution.

run regedit
  Change the following key value:
  Computer\HKEY_LOCAL_MACHINE\SYSTEM\
       CurrentControlSet\services\TCPIP6\Parameter\DisabledComponents
I changed the value from 0 to 0xff
I rebooted
The ghost lan connections disappeared (but I was missing IPv6)

run regedit a 2nd time
changed the value back (from 0xff to 0)
I rebooted
Now IPv6 works again
And the ghost lan connections are still gone

Here are some ways that did not help.

Thanks for the "reset" suggestion, but it did not work.  Here is what I received:

1) netsh interface ipv6>reset
There's no user specified settings to be reset.

2) I completely disabled IPv6, as follows:

2a) Via network adapters -> properties, I unchecked IPv6 on my two network adapters.

2b) via Microsoft's fix it 50444, I disabled all IPv6 tunnels:
   see http://support.microsoft.com/kb/929852

I rebooted.  The above did not solve the problem.

3) I searched the registry for "Local Area Connection"
I found them all at Computer\HKEY_LOCAL_MACHINE\ControlSet001\Control\Network\...

I deleted almost all of them manually.  Rebooted.  However this did not solve the problem.

If anyone finds a more elegant solution, to delete just a few of the unused ghost IPv6 connections, post the solution here.

Thanks!

I fixed a similar problem by going to device manager, going to view -> Show hidden devices.  Expand the Network adapters node.  Then uninstall Microsoft Direct Point-to-point Adapter and the Microsoft ISATAP adapter.  Then in netsh the adapter should be gone.  After you add the adapter again you might need to delete the address and the route before doing the last 2 commands provided as an example config.

You had the answer on the URL you posted ttp://support.microsoft.com/kb/929852

If you had changed the value to "Type 0x01 to disable all tunnel IPv6 interfaces." and left it like that they would not be back and IPv6 for the lan interface would continue to function...

Hi.

Hi, I searched high and low over the internet and couldn't find a way to remove these phantom interfaces.
I tried registry edits and reboots, but if you use the registry settings above ie: 0x01 or 0xff you will lose to ability to tunnel anything.

I've discovered that the only way to remove these phantom interfaces is actually quite simple, and painless,

1) Fire up devmgmt.msc, start->run->devmgmt.msc .
2) In devmgmt.msc console select "view" then, "show hidden devices" .
3) Scroll down the hardware list until you see "Netwrok Adapters", expand this tree.
4) Proceed, to delete your phantom, or unwanted connections, mostly you'll be looking for ISATAP.
5) Take a short minute to reply if this helped you.

I trust this will help.

Thank you kindly,
