Does anyone know of a true, authentic, network diagnostic utility for Windows 7. The script provided by Microsoft was written by 1st graders as a project. I need to know why I can see and detect my laptop, but I can't connect to it. Both system use Win 7 Pro x64, and are part of the same homegroup. The Public and Home Group settings on both are identical. Should I remove Microsoft's Networking capabilities and install a 3rd party software like Cisco' Network Magic? Please Help!
