Device Does Not Appear in WinDiscovery

Symptoms

• The device does not appear in WinDiscovery
• WinDiscovery does not find any devices on the network

Causes

• PC and device are on different subnets or VLANs, and discovery traffic does not cross the boundary
• Firewall rules on the PC or network block discovery traffic
• The device is still booting or is renegotiating network settings
• The device is using fallback addressing due to missing DHCP

Troubleshooting steps

1. Confirm the PC and device are on the same network segment. In most environments, discovery works best when both are on the same subnet.
2. Temporarily allow WinDiscovery through host firewalls. If discovery works after adding an approved application exception, have IT retain the required rules.
3. Allow time for boot and network initialization. If the device was just powered on or moved to a new network, wait for it to complete network initialization.
4. Check for fallback addressing. If the device shows a 169.254.x.x address, see Understanding Fallback IP Addresses (169.254.x.x).
5. Learn how discovery works. See How WinDiscovery Discovers Devices on the Network.
