Greetings,

I have a win vista machine with a problem with its networking components.

In device manager the lan and wifi adapters show exclamanation points and then for status say "the device is not working properly because windows cannot load the drivers required"

There are also 8 "6TO4 Adapter" listed that I cannot get rid of.  It doesn't look normal.

I suspected the machine had spyware and it did.  But now I still can't make any headway on restoring the wired or wireless networking.

It shows the same in safe mode as well.

Thanks for any insight.

Are you on an 802.1x compliant network?
Is this a x64  bit OS on this machine?

It sounds like you had this working before or the 6 to 4 adapters wouldn't be there (explained later). If so, I have noticed some of my machines get both wireless and wired network apapter bindings mixed up. I had to reset the IP stack and Winsock to get them functional again. Out of over 10000 machines, only a handful experienced this problem.

The 6 to 4 adapters are called a teredo tunnel, and nothing to be alarmed about. As long as you use IPv6 on an IPv4 network, they will reappear, if you delete them.

It looks like you are trying to run IPv6 on your IPv4 network. Every time you turn on your computer a new adapter could appear to try and encapsolate IPv6 traffic in an IPv4 packet and another 6-4 adapter will appear.

To correct your regular wired and wireless networking, try running System File Checker.

Run SFC /SCANNOW and allow to complete. Run again if errors remained from the first run. Restart the computer after this.

If no luck, can you restore to a prior point?

If the virus did enough damage, you may have to re-install Vista. In this event, consider moving on to Windows 7.

Can you restore it to the day from 'System Restore' when it was working perfectly fine?

maybe easier - and faster -to do a fresh install, or factory reset on the system
AFTER a proper backup !

file scan didn't do it.  But rolling back was successful.

Thank you.
