What is network discovery?Network discovery is a network setting. This setting can determine if your computer can find other computers and devices on the network and also if other computers on the network can find your computer.There are three network discovery states:OnThis state allows your computer to see other network computers and devices and allows people on other network computers to see your computer. This makes it easier to share files and printers.OffThis state prevents your computer from seeing other network computers and devices and prevents people on other network computers from seeing your computer.CustomThis is when you can customize some settings related to network discovery. Network discovery requires that the DNS Client, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host services are started, that network discovery is allowed to communicate through Windows Firewall, and that other firewalls are not interfering with network discovery. If some but not all of these are true, the network discovery state will be shown as Custom.To turn on network discoveryGo to Control PanelAll Control Panel ItemsNetwork and Sharing CenterAdvanced sharing settings Click the drop down arrow to expand the current network profile.Click Turn on network discovery, and then click Save changes.

Network discovery is not a single thing. In general terms it is the process of gathering information about the Network resources near you. It consists of a group of protocols that all report to the Function Discovery platform. Probably the most well-known protocol is NetBIOS Browsing, but it also includes WSD, UPNP, SSDP, and even the registry. Typically you see this information in Network Resources/Network Neighborhood, but any application can potentially be programmed to use it.
