Why network Discovery is disabled on public networks? Question : Why network Discovery is disabled on public networks? Answer : With Network Discovery, users can browse shared network resources from the Network window. On private networks, this is convenient because users can connect to resources without knowing the names of other computers on the network. On public networks, however, Network Discovery has a security concern, as it will announce the presences of the computer on the public network, and users might use it to connect to a potentially malicious computer. For these reasons, Network Discovery is enabled on private networks but disabled on public networks by default
