Windows network errors can be frustrating, especially when you are trying to access shared folders, network drives, remote devices, or servers. One common issue many Windows 11 users encounter is Error 0x80070043: The Network Name Was Not Found. This error typically appears when your system cannot locate or connect to a specified network path, shared folder, mapped drive, or remote resource.
This problem can interrupt business workflows, home networking, file sharing, printer access, and remote server communication. It may occur due to incorrect network paths, DNS issues, disabled services, outdated drivers, SMB protocol conflicts, firewall settings, or corrupted system files.
Fortunately, this error is usually fixable through a series of practical troubleshooting steps. Whether you are a beginner or advanced user, resolving this issue often involves checking network connectivity, enabling essential services, repairing system files, and adjusting sharing configurations.
This guide explains how to diagnose and fix Error 0x80070043 on Windows 11 using reliable methods that restore stable network functionality.
What Causes Error 0x80070043?
This error generally means Windows cannot locate the network resource specified in the path.
Common causes include:
- Incorrect network path
- Shared folder no longer available
- DNS resolution issues
- Disabled network discovery
- Firewall restrictions
- SMB protocol problems
- Network adapter driver corruption
- Credential mismatches
- Workgroup configuration errors
- Windows update conflicts
- Disabled services like Workstation or Server
- VPN or security software interference
Understanding the cause is essential for choosing the right fix.
Verify The Network Path
The first step is ensuring the shared resource path is entered correctly.
Example network path:
\\ComputerName\SharedFolderOr:
\\192.168.1.10\SharedFolderCheck for:
- Misspelled device names
- Incorrect folder names
- Invalid IP addresses
- Offline target devices
Using the IP address instead of hostname can help identify DNS-related issues.
Test Basic Network Connectivity
Before deeper troubleshooting, confirm the remote device is reachable.
Steps:
- Press Windows + R
- Type:
cmd- Use:
ping ComputerNameor
ping 192.168.1.10If ping fails:
- Check router connection
- Verify Wi-Fi or Ethernet status
- Restart both devices
- Confirm target machine is powered on
No connectivity means the network issue must be solved first.
Enable Network Discovery
Network discovery allows Windows devices to find each other.
Steps:
- Open Control Panel
- Go to Network and Sharing Center
- Select Advanced sharing settings
- Turn on:
- Network discovery
- File and printer sharing
Benefits:
- Detects network devices
- Improves folder access
- Restores shared resource visibility
Without discovery enabled, Windows may fail to locate devices.
Restart Essential Network Services
Several Windows services are critical for network access.
Steps:
- Press Windows + R
- Type:
services.mscEnsure these services are running:
- Workstation
- Server
- DNS Client
- Function Discovery Provider Host
- SSDP Discovery
- TCP/IP NetBIOS Helper
Set startup type to:
- Automatic
Restarting these services often restores access.
Clear DNS Cache
Corrupted DNS cache can prevent network path resolution.
Steps:
Open Command Prompt as Administrator and run:
ipconfig /flushdnsThen:
ipconfig /release
ipconfig /renewBenefits:
- Refreshes IP configuration
- Resolves hostname conflicts
- Improves network recognition
Check SMB Protocol Settings
SMB (Server Message Block) is essential for Windows file sharing.
Older devices may require SMB 1.0
To enable SMB:
- Open Control Panel
- Go to Programs and Features
- Select Turn Windows features on or off
- Enable:
- SMB 1.0/CIFS File Sharing Support
Important:
SMB 1.0 is outdated and less secure, so only enable it if absolutely necessary.
Modern systems usually rely on SMB 2 or SMB 3.
Disable Firewall Temporarily
Firewall settings may block network sharing.
Steps:
- Open Windows Security
- Go to Firewall & network protection
- Temporarily disable firewall
- Test connection
If successful:
Add exceptions for:
- File and Printer Sharing
- SMB traffic
- Network discovery
Do not leave firewall disabled permanently.
Reset Network Settings
Windows network corruption can cause persistent issues.
Steps:
- Open Settings
- Go to Network & Internet
- Select Advanced network settings
- Choose Network reset
This will:
- Reinstall adapters
- Reset configurations
- Remove corrupted settings
Restart your PC afterward.
Update Network Adapter Drivers
Outdated or corrupted drivers can trigger network errors.
Steps:
- Right-click Start
- Open Device Manager
- Expand Network adapters
- Right-click adapter
- Select Update driver
You can also:
- Uninstall driver
- Restart PC
- Let Windows reinstall automatically
Updated drivers improve compatibility.
Check Shared Folder Permissions
If permissions are incorrect, access may fail.
On the host PC:
- Right-click shared folder
- Select Properties
- Go to Sharing tab
- Confirm sharing is enabled
- Check Security permissions
Ensure:
- Correct user accounts are authorized
- “Everyone” has appropriate access if needed
Use Credential Manager
Stored login credentials may be outdated.
Steps:
- Open Control Panel
- Go to Credential Manager
- Remove old network credentials
- Reconnect to the shared device
This can resolve authentication mismatches.
Run System File Checker
Corrupted Windows files can disrupt networking.
Open Command Prompt as Administrator:
sfc /scannowThen:
DISM /Online /Cleanup-Image /RestoreHealthBenefits:
- Repairs system files
- Fixes Windows networking components
- Resolves deeper corruption
Disable VPN Or Security Software
VPNs and third-party antivirus programs may interfere with local network access.
Try:
- Disconnecting VPN
- Disabling antivirus temporarily
- Retesting shared folder access
If resolved, adjust software settings.
Common Error Scenarios
Accessing NAS devices
- Enable SMB compatibility
- Update NAS firmware
Mapped drives disconnected
- Reconnect drive
- Verify credentials
Office network issues
- Check domain policies
- Verify DNS servers
Home sharing failures
- Confirm same workgroup
- Restart router
Prevent Future Network Name Errors
To reduce future problems:
- Keep Windows updated
- Maintain updated drivers
- Use stable IP assignments
- Verify network paths
- Backup network settings
- Avoid outdated SMB versions when possible
- Monitor router health
Regular maintenance improves long-term reliability.
Final Thoughts
Error 0x80070043: The Network Name Was Not Found can be disruptive, but in most cases it is caused by manageable issues such as network path errors, DNS failures, disabled services, firewall restrictions, or outdated protocols.
By systematically checking connectivity, verifying shared paths, enabling discovery, resetting network settings, updating drivers, and repairing Windows components, most users can restore normal access without major complications.
Whether you are managing home file sharing, office networks, or server access, these troubleshooting methods provide a reliable path to solving the problem and improving network stability on Windows 11.
