I have installed Windows 7 on my PC and laptop. One problem I have though is that I have created a Homegroup on my PC, I have a password and all seems fine, but on the laptop it does not recognise that there is a Homegroup on the network. If I try to create a Homegroup on the laptop I get the message: "Your network connection must have IPv6 enabled to create or join a homegroup. To enable IPv6, start the HomeGroup troubleshooter." The thing is, I DO have IPv6 enabled!! Any ideas?
