Hi,
This issue occurs for one of the following reasons:
•The dependency services for Network Discovery are not running.
•The Windows firewall or other firewalls do not allow Network Discovery.
To resolve the issue, follow these steps:
1.Make sure that the following dependency services are started:
- DNS Client
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host
2.Configure the Windows firewall to allow Network Discovery. To do this, follow these steps:
- Open Control Panel, click System and Security, and then click Windows Firewall.
- In the left pane, click Allow a program or feature through Windows Firewall.
- Click Change settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Select Network discovery, and then click OK.
3.Configure other firewalls in the network to allow Network Discovery.
4.Turn on Network Discovery in Network and Sharing Center
