Hi hope someone can help......I have installed W7 on a desktop and laptop and have set up a homegroup but am unable to see anything in the homegroup folder and either PC's please help!!!!!

Hi, I suggest that you temporary disable the anti-virus and firewall. If the issue persists, check if you can access Internet from the Windows 7 beta computers. If not, check if you have set IP address and DNS properly. If the settings are correct, I suspect that the issue is caused by the network adapters' drivers that are not compatible with Windows 7 beta. However, if you could access Internet, I suggest that you open Control Panel->Network and Sharing Center->Advanced sharing settings, turn on everything. Hope it helps. Arthur Xie - MSFT
