My Vista PC has two Ethernet adapters: one is connected to the Internet, and one to a LAN. In the Network and Sharing Center I've configured the first to be a Public Network and the second to be a Private Network.
When I try to enable File Sharing, Vista offers me to turn the first network into a Private Network, or to enable File Sharing for all Public Networks. I don't want any of these options; I want to enable File Sharing for the LAN connection but not for the Internet.
How do I enable File Sharing only for Private Networks but not for Public Networks?
