my computer wont look for other computers on network

Answer 1

Hello, I’m Quinn and here to help!

To better understand the issue, could you please confirm whether you’re using Windows 10 or Windows 11, and whether the connection is Wi-Fi or Ethernet? Also, can other computers see this PC, or is it not visible both ways? In the meantime, please try the following steps:

Open Control Panel

1. Go to Network and Internet > Network and Sharing Center

On the left, click Change advanced sharing settings

Under Private network:

1. Turn on Network discovery
2. If it still doesn't work, try uncheck the box Set up network connected devices automatically

Under Public network:

1. Temporarily turn on Network discovery for testing purposes only
2. If this resolves the issue, switch it back off afterward, as Public networks are intended to keep your PC hidden for security

Answer 2

If your computer is not able to look for other computers on the network, it might be due to the firewall settings or network discovery settings. Here are some steps you can take to resolve the issue:

1. Check Firewall Settings: Ensure that your firewall is not blocking file and print sharing. You may need to configure your firewall to allow the necessary ports for network discovery. The ports associated with file sharing and SMB communications include:
   • UDP ports from 135 through 139
   • TCP ports from 135 through 139
   • TCP and UDP port 445
2. Enable Network Discovery: Make sure that Network Discovery is turned on in the Network and Sharing Center. If you cannot turn it on, it might be due to dependency services not running or firewall settings preventing it.
   • Check that the following services are running:
     • DNS Client
     • Function Discovery Resource Publication
     • SSDP Discovery
     • UPnP Device Host
   • Configure the Windows firewall to allow Network Discovery.
3. Use a Router or Firewall Configuration: If you are using a firewall on a network connection that connects to both the Internet and a home or office network, ensure that it is configured to allow local network traffic.

By following these steps, you should be able to enable your computer to find other computers on the network.
