Repair Microsoft TUN Miniport Adapter???

[Guest]

OS - WindowsXP Pro, fully patched.
According to MSDN, the TUN Miniport adapter is a SP2 "feature."
I recently noticed in the Device Manager that the Microsoft TUN Miniport
Adapter has a yellow exclaimation point. (In Safe Mode, it does not.)
I tried to ininstall the adapter so it would reinstall but it is locked in
both normal mode and in safe mode. I can disable it, but so what? I tried
uninstalling TCPIP v6. ZAZULA at Tech Support Forums posted a way to remove
it from the registry, but I want to fix it.
I have found no repair instructions on the web that work. I ran various
networking utilities, nothing I found provided a cure.
How do you repair this adapter?

If you don't mind a wild guess, It could have something to do with your
Winsock catalog. Couldn't hurt to try a simple fix for winsock to see if it
helped.

the netsh command in SP2 can rebuild the Winsock catalog. Open the command
prompt and type: netsh winsock reset catalog then press ENTER.

Thanks for the suggestion. Unfortunately, neither netsh winsock reset
catalog nor netsh interface ipv6uninstall helped.
Others suggested checking Services. However I could not find one that is
relevant.
TUNMP.SYS is on this system and is the latest version as far as I can tell.
It matches the version on my other machines. This "feature" is huwee!
MICROSOFT WHAT IS THE FIX?

I tried numerous fixes. What finally worked was to use the add new hardware
wizard, select the TUN adapter device with the yellow exclaimation point, go
through the troubleshooting wizard, get to the list of compatible devices
(DON'T merely update), install a compatible TUN adapter, and voila the broken
device is fixed. So simple and obvious in hindsight.
ZAZULA at Tech Support Forums, I take your year of bragging rights. My cure
is simpler and the device survives the procedure!
