I recently installed Windows 7 (32 bit) over Vista on my Dell desktop. I have now bought a laptop with Windows 7 (64 bit) pre-installed, I have tried to set up a home group using the desktop, but it tells me that I need ipv 6 to do so. Local Area Network Status shows ipv 6, but says that there is no network access. I would welcome any help, bearing in mind that I am a cowardly novice.

Many thanks
