Hello,
I have an Amilo Li1705 with Vista as OS. The problem is that it often crashes: the monitor freezes and I can only reboot. I brought it back to the shop and they gave me an other one. But it has the same problem.
In the settings/network adapters I see there are several instances of "Microsoft 6to4 Adapter". Each time I delete or switch off these adapters afterwards more of the seem to be installed automatically. I don't know whether this has to do with the constant freezing of the machine.
Thanks for helping.
