How do I fix the 0x8007003b error on Windows 10?

The network error code 0x8007003b can be due to malware. So, a full virus scan might resolve the issue. You can utilize Windows Defender to scan for malware since it’s already built-in.

However, for more advanced and accurate results, we recommend trying third-party antimalware software for Windows 10.

2. Temporarily Switch off Anti-Virus Software

  • Press the Windows key, type virus, and click Virus & threat protection.
  • Click the Manage settings option.
  • Finally, toggle the switch for the Real-time protection option backward to disable it.

If a malware scan didn’t fix the network error code 0x8007003b issue, temporarily disable your third-party antivirus software. The antivirus software could be interfering with the file transfer.

If it is a third-party antivirus, you can usually switch it off by right-clicking its system tray icon and selecting a disable option on its context menu.

3. Switch the Windows Firewall off

  • Click the Start icon, type firewall, and click Windows Defender Firewall.
  • Click Turn Windows Firewall on or off in the left pane.
  • Now, tick the Turn off Windows Firewall radio buttons for both the Private and Public options.
  • Finally, click the OK button and restart your PC.

The Windows Firewall can also get in the way of file transfers. It is, after all, a network wall of sorts; so switching that firewall off could fix the network error code 0x8007003b.

4. Disable the Windows Search service

  • Press the Windows key + R, type services.msc, and click the OK button.
  • Right-click the Windows Search service.
  • Now, select the Stop option.

According to some users, the Windows Search service can also cause the network error code 0x8007003b. You should temporarily disable the service and try sending your files again.

5. Check the Destination Hard Drive’s Format

  • Launch File Explorer and right-click your hard drive.
  • Select the Properties option.
  • Now, check the File system type.

Another thing to note is if the destination hard drive for the file is FAT32 formatted. You can’t transfer files larger than 4 GB to a FAT32 hard drive.
