Solve Network Discovery keeps turning itself back OFF by Running the Services

According to Microsoft, there are four services that must be running on the server in order to Discover other Devices or to be Discovered by others on a network. And Here are these Services:

  1. DNS Client
  2. Function Discovery Provider Host (FDPHOST)
  3. SSDP Discovery
  4. UPnP Device Host

Now you may be thinking what are these services and what are the connections between them.

  • DNS Client: The DNS Client service is a service which solves and caches Domain Name System (DNS) domain names. It receives a request to solve a DNS name that it is not contained in the cache, it queries an assigned DNS server for an IP address for the name.
  • Function Discovery Provider Host (FDPHOST): These Function Discovery (DP) providers, supply network discovery services for the Simple Service Discovery Protocol (SSDP) and Web Services.
  • SSDP Discovery: SSDP stands for Simple Service Discovery Protocol. SSDP which is the foundation of the discovery protocol For Universal Plug and Play (UPnP), is pretended for use in local or small office environments.
  • UPnP Device Host: UPnP stands for Universal Plug and Play. UPnP is a service which allows UPnP devices to be hosted on the computer. If it stopped devices will stop functioning, that time you are not able to add additional hosted devices.

Now that know what are those services and How they are linked with Network Discovery, it is time to enable those Services.

Follow the Procedures to enable these Service:

Step 1. Open Server Manager, navigate to Tools and select Services.

Step 2. When the Services page opens, Find the DNS Client. If you want to find quickly, press D on the Keyboard it will take you to services which are started from D.

Step 4. After visiting the Properties tab, find it status from Manual, or Disabled to Automatic. When you did that, select start to start the Service.

Changing the Status

Apply the same settings for other three services. After applying all the services Go ahead and check Network Discovery it is turned on, if that is not turned on and you are facing again the same problem then Solve the Error using Group Policy which is the Method I have introduced.
