Windows Firewall can't change settings, error 0x8007042c

Looks like the IPv6 protocol on the computer was disabled using the Registry.

Please press the Windows key and the R key.
In the Run prompt, type in: regedit

In the Registry Editor please go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP6\Parameters

Before making any change to the Registry key, back it up, so the Registry subkeys containing values that you're planning on changing are not lost.

In the Registry Editor menu, select File and then Export....

In the Export Registry File window that appears, select the Desktop as the location to save the file.

Using the File name text field, enter a name for the backup file. Make the name whatever you wish. (Example: Parameters)

Click the Save button, and a Registration File with a .reg file extension is created on the Desktop.

When we are done, and all is well, right-click the file, and select: Delete

Please do not double-click the .reg file, since the action will reinstate the previous entry in the Registry!


Now, highlight and right-click: DisabledComponents
Select: Modify

In the Edit DWORD Value prompt, Value Data area, set the value to 0 (that is zero)


Restart the computer.

Run SystemLook the same as before, and post the new SystemLook.txt in your reply.

Let's take it back to what it was.

Please go back to the .reg file created on the Desktop, and double-click it.

Agree to merge the entry into the Registry.

Restart the computer, and run SystemLook once again.

Please post its results.

Merging the Registry entry reinstates it. That is what you did.

Is your Internet connection via Ethernet OK now?

Good! Glad it is working.

Everything is working fine so I think I'll leave it as is. I feel that tinkering with it and trying to fix it might cause more problem than it's worth.

You may want to post the Teredo Adapter issue in the following forum:

Someone there may be able to provide you assistance the heck of a lot better than what I can in this System Security forum.
