In my building we three friend living, all of us having our personal laptop. We create a home group network service, which can only use by us. We all configure our machine with the network. I am using a windows 7 compatible Dell inspiron laptop. They problem is I am not able to connect my machine with that home network. Though one of my friends also using the same operating system, his machine is connected easily. Then why I am not able to connect. I am not having any technical idea about this type of problem, so I am here to getting some solution for this problem. How to connect my machine with the same home group network wizard? Is there anyone have any trick or information regarding this topic?
