Well as the title of the thread is suggesting what I wanted to discuss over here. I have installed Windows 7x64 on the computer of mine. I let you know that I am having an issue with Microsoft ISATAP Adapter as well as Toredo Tunneling Adapter. I am getting an error code 10. I cant figure out the root cause of the problem. Let me know if you are having any useful to figure out the root cause of the problem. Any help on this particular matter will be highly appreciated. Thanks a lot in advance.
