How to fix
“Network Discovery is turned off” error
on Windows

Hey everyone, I'm running into an issue on my Windows PC where it keeps saying "Network Discovery is turned off" every time I try to view other devices on my network. I'm not sure what caused this or how to fix it. Could really use some help getting Network Discovery working again.

Windows' essential Network Discovery function enables PCs and other devices to locate one another on a network. This function is essential for smooth communication between devices connected to the same network, as well as for sharing files and printers. If Network Discovery is enabled, your device can engage in network activities, be visible to other devices, and be able to locate others. But occasionally, users run into a problem where Network Discovery is turned off, which might impair sharing and connectivity.

The "Network Discovery is turned off" error typically appears when attempting to access network resources like shared folders or printers, effectively isolating the device from network interactions. This error can arise from various scenarios including changes in network settings, recent updates, or security software interventions. It's a common problem that signals the device's inability to communicate over the network, necessitating a dive into settings to rectify the situation.

Addressing the "Network Discovery is turned off" error usually involves navigating the Windows settings to manually turn Network Discovery back on. However, the cause might be more complex, involving network policies, firewall settings, or services that are essential for network discovery and file sharing.

For example, services such as DNS Client, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host play critical roles in the proper functioning of Network Discovery. If these services are disabled or malfunctioning, Network Discovery might not work as expected.

Furthermore, firewall configurations can block the necessary network discovery features. Adjusting firewall settings to allow for network discovery and file sharing is often required to resolve this issue. In environments with multiple network profiles (private, public, and domain), the settings for each can affect how Network Discovery operates, necessitating a review and adjustment of these profiles to ensure that Network Discovery is enabled for the correct network type.

Fix 1. Enable Network Discovery in Network and Sharing Center

This enables your computer to see other devices and be seen on the network.

• Click on Start and pick Settings.
• Go to Network & Internet.
• Select Advanced sharing settings on the left pane.
• Expand your current network profile (Private, Guest, or Public).
• Turn on network discovery and also check Setup of network connected devices automatically checkbox.

Fix 2. Start the necessary services

Certain services must be running for Network Discovery to work.

Fix 3. Configure Windows Firewall

Ensuring Windows Firewall is not blocking Network Discovery.

• Open the Control Panel, go to System and Security, then Windows Defender Firewall.
• Click Allow an app or feature through Windows Defender Firewall.
• Click Change settings (you might need administrator permission).
• Ensure Network Discovery is allowed for Private and Public networks.
• Click OK after enabled.

Fix 4. Use Network Troubleshooter

Running the built-in troubleshooters can resolve network issues.

Fix 5. Turn off third-party security software

Third-party antivirus and firewall programs can interfere with network discovery.

• Temporarily disable any third-party antivirus or firewall software you are using.
• Check if this resolves the issue. If so, consider adjusting the software’s settings or switching to another program.

Fix 6. Reset network settings

This can resolve underlying network configuration issues.
