MS Tun miniport adapter in XP

[t1k1]

I have looked everywhere to fix this problem and just found this cool place to ask a question.

I have a Iomega CD/RW external drive which used to work fine with my IBM Thinkpad R31 running Windows XP SP2.
Then a few days ago it quit working, Device Manager tells me the device is Unknown, and I have a network adapter called Microsoft Tun Miniport Adapter #2 with a yellow exclamation point, with error code 10.

I have looked on Microsoft's website, Google and lots of places and I can't get my Iomega CD/RW drive to connect and work.

Any new ideas?

Thanks!

We've been experiencing something similar here, but not with the same hardware as you're using. Ours appears more often with USB ADSL modems.

I know that you won't be able to remove the 'Microsoft Tun Miniport Adapter #2', as Windows sees it as a device required for booting(?).

After extensive research, I've found out this component is part of IPv6. IPv6 appears to be available with SP2, but may've also been available via an earlier service pack or hotfix.

If you're not using IPv6 (I assume you wouldn't be), you can uninstall it by executing the following command (I recommend doing such in a a Command Prompt):

ipv6 uninstall

If IPv6 was installed at the time of execution, you will see...

Uninstalling...
A reboot is required to complete this action.

Restart your PC to complete the process, as advised.

With IPv6 uninstalled, you _may_ be able to remove 'Microsoft Tun Miniport Adapter #2' from Device Manager.

If not, there's certain registry keys that can be deleted to prevent the service from starting up during Windows' boot.

ANYTHING PERFORMED BELOW IS DONE AT YOUR OWN RISK...

Perform a search for 'tun miniport' in Registry Editor (Start - Run - regedit) and delete the resulting keys. When doing a search on my PC, the following keys are returned:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\t unmp
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\t unmp
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\tunmp

Yours may be a little different - not sure.

Restart your PC after deleting the registry keys and see whether 'Microsoft Tun Miniport Adapter #2' is still present in Device Manager.

Please provide feedback, as this solution has _not_ been tested with the 'Code 10' error...

I run the internet of a Router connected to 3 different PC's, i found the "Microsoft Tun Miniport Adapter" in my device manager and it read "Code 10, cannot start", so i uninstalled the IVp6 and restarted but i still have no luck, what can i do now?

If you're game, you can go through the process of removing the mentioned registry entries. I suggest you back up the registry keys before going ahead, in case anything goes bad. As I've said, the registry modification is untested.

Also, ensure you haven't bridged any two network cards inside Network Connections. Apparently, this can also cause Tun to appear.

All fine and well, but I'm 99% sure that the miniport issue is unrelated to the cdrw issue.
-Is the drive appearing in device manager? If so, what error message are you getting?
-Assuming the drive connected via usb, do you have an external power source connected? Do other usb device work properly?
-Have you tried flashing the bios to latest version?
-Latest chipset drivers installed?
-Can you try the drive on another computer?

HI Stebie I don't have any of those entries in my registry, yet I still have the tun miniport #2 and no matter what I done it does not let me uninstall it.

Well gang I finally got rid of all the tun miniports adapters I had in my pc.
I am using XP Pro, and this is how I did it.
First I uninstalled SP2, then I rebooted my XP PRo CD and when I selected install windows it gave me two options, new install or upgrade, I selected upgrade, it looks like it did a good repair and did not delete any of my programs, then I did all the XP updates (SP2,etc) and when it was finished no more TUN Miniport adapters.
Don't know if what I did will work for everybody, so be careful, all I know it worked for me.
Now I will like to find out what was that installed them and why they can't be uninstalled easily , except the tcip/6 via the uninstall command

I have had the same problem and really don't know why? The solution is simple: Go to "network Places" and look at properties of connections. Besides "Client for Microsoft Networks", "File and Printer Sharing...", "Microsoft TCP/IP", etc., there is an entry with the name "Microsoft TCP/IP version 6". Just uninstall this and the problem should be gone.

I can't say anything about the others, but this one works great. Thanks!!!!
