I'm having problems with my Eset Smart Security 4 that comes with a firewall. I'm sharing my 2 laptops with Windows 7 RC1 and trying to connect thru Homegroup. My first laptop uses Eset Smart Security and the other one uses Windows Firewall. When I try to connect both with Homegroup, I cannot detect it. When I disable the "Firewall of the Eset Smart Security", the Homegroup start to function properly. It detects the files what I share. But then I want to Enable the Firewall of the Eset. Whenever I enable it, the Homegroup doesn't function. I don't know how to create RULES or EXCEPTIONS on the firewall. Please someone help me. Give me instructions. Sorry for my bad english. Thank you very much.
