You need to define your network zone to all the ip of the lan (eg and sometimes also allow localhost at

The networking rules must be established in this range for the 3 protocols: tcp/udp, icmp, ip.

Depending on the OS of your lan pc, the application rules must allow rsvp, svchost, system and explorer for the same local network zone.
