I uses Acer Aspire 5920, I found in my Device Manager a named Microsoft ISATAP Adapter device driver error exclamated with yellow which is an indication that all is not well. I did not install any adapter to my notebook computer, so how come about this strange device in my system? Please if anyone out there has experience this same problem, please advice on how to solve it, I've asked windows to look for the driver to the Microsoft ISATAP Adapter in the internet but the result was not successful. Where can I find and download the driver for this Microsoft ISATAP Adapter? Please mail me the link. Peter Agboro
