I'm having a problem setting up home group. My home sever pc (win7 Home Premium) connects directly to the internet, I shared it's internet connection to one of its ethernet (lan) cards which is then plugged directly into the WAN port on my wifi router using a cross-over network cable. All the computers (win7) in the house connects to the wifi router and can access the internet fine and see each other in windows Home Group, but none of them can see my home server pc. please help.
update: could it be a router setting?
