Hi all I installed Privatefirewall on my main PC (Windows 7) after deciding I really ought to start using one and reading a review which sounded promising and I liked it - until I realised that my Homegroup connection out of the PC is fine but all of the many, many laptops (mixture of 7 and 8) in the household have difficulty getting into the PC. The standard Network is fine in both directions, but Homegroup is out only for the PC with Privatefirewall. Turning the firewall on and off turns the connection to Homegroup on and off so I'm pretty sure it's the problem. I have tried to go through an elimination process to determine which if any controllable setting is responsible and have got as far as unticking everything in the Network Security without effect. Part of the annoyance is that I had finally got around to resetting the Homegroup on all the machines so they could all see and share with each other. Any tips, pointers or definitive answers gratefully received.
