If your Windows 10 computer name isn't showing up on the network, it can make file sharing, remote access, or printer sharing difficult. This issue is common in home or small office networks and usually stems from network discovery settings, services, or name resolution problems. Here's how to troubleshoot and fix it.

? 1. Enable Network Discovery and File Sharing

Windows 10 may have network discovery turned off by default, which hides your computer from others.

Steps:

• Press Win I to open Settings .
• Go to Network & Internet > Ethernet (or Wi-Fi , depending on connection).
• Click on the active network connection.
• Under Network profile , make sure it's set to Private (not Public).
  • Public profile disables discovery for security.

Now enable discovery:

• Open Control Panel > Network and Sharing Center > Change advanced sharing settings .
• Under Private network profile:
  • Turn on Network discovery
  • Turn on File and printer sharing
• Click Save changes .

? You may need to restart your computer for these changes to take full effect.

? 2. Ensure Necessary Services Are Running

Several background services are required for your computer to appear on the network.

Check these services:

• Press Win R , type services.msc , and press Enter.
• Verify the following services are Running and set to Automatic :
  • Function Discovery Resource Publication
  • SSDP Discovery
  • UPnP Device Host
  • Computer Browser (if present)
  • DNS Client
  • Function Discovery Provider Host

?? If any are stopped, right-click → Start . Then double-click to set Startup type to Automatic .

? 3. Verify Computer Name and Workgroup

Even if discovery is on, incorrect naming or workgroup settings can prevent visibility.

Check your computer name:

• Right-click This PC > Properties .
• Confirm the Computer name is set and makes sense (eg, MYPC ).
• Ensure all computers are in the same Workgroup (usually WORKGROUP by default).
  • Change if needed via Change settings under "Computer name, domain, and workgroup settings".

? After changing name/workgroup, a restart is required.

? 4. Use Network Reset (if other fixes fail)

Sometimes network configurations get corrupted.

Try a network reset:

• Go to Settings > Network & Internet > Status .
• Scroll down and click Network reset .
• Click Reset now → confirm.

? This will remove and reinstall all network adapters and reset settings to default. You'll need to reconnect to Wi-Fi afterward.

? 5. Access by IP or Full Computer Name (Workaround)

Even if the computer doesn't appear in Network in File Explorer, you can still access it directly.

Try this in File Explorer address bar:

 \\ComputerName

or

 \\192.168.1.100 ← (replace with the actual IP of the target computer)

To find the IP:

• On the target PC, open Command Prompt and type:

   ipconfig

• Look for IPv4 Address under your active connection.

? Tip: Assign a static IP to avoid changes after reboot.

? 6. Firewall or Antivirus Blocking Discovery

Third-party firewalls or security suites may block network discovery traffic.

• Temporarily disable antivirus/firewall to test.
• Ensure Windows Defender Firewall allows File and Printer Sharing :
  • Go to Control Panel > Windows Defender Firewall > Allow an app through firewall .
  • Make sure File and Printer Sharing is checked for Private (and maybe Public, if needed).

Summary Checklist

• [ ] Network set to Private
• [ ] Network discovery and File sharing enabled
• [ ] Required services running
• [ ] Correct computer name and workgroup
• [ ] Firewall not blocking discovery
• [ ] Tried accessing via \\ComputerName or \\IP

---

It's not always necessary for a PC to show up in the "Network" section — as long as you can access shared folders using the computer name or IP, functionality is intact. The visibility in File Explorer is more of a convenience feature and can be finicky.

Basically, fix the settings above, and most of the time, it'll start appearing — or at least be accessible.
