I am trying to link my xbox360 to media center, but my windows live one care firewall is stopping them from linking. Someone else tried to fix it, but ended up "clearing unconnected" options and I can't seem to get them back. My firewall is on public and needs to be on home or work.. Please help.
Open One Care>Change Settings>Firewall>Configure Firewall>Change Location, then select "Home or Work". Select "Advanced Settings" and on the "Ports and Protocols" tab check "Xbox 360 and Network Media Players".
