I recently purchased a Dell PC and a Dell Laptop both running Windows 7 Software. After carefully constructing the HomeGroup the Laptop is still unable to communicate with the PC although it can see the folders. I have checked the permissions etc and all is the same on both the PC and Laptop. The Firewall settings are the same as well. Finally after many hours of leaving the group and setting it up time and time again i was able to see the Files shared by the PC however was unable to access the Laptop files from the PC .. Finally i introduced another Laptop running Windows 7 into the HomeGroup and achieved full functionality with the PC although still nothing with the Initial Laptop... I have checked everything i can think of .. Could the Laptop be faulty.. I am running a different Anti virus software on the Laptop.. could this be blocking the HomeGroup operation.. any help would be much appreciated.
