There are a few possible solutions to the error 0x8007003b.

How to solve a network fault 0x8007003b

Malware Scanning

Because Error 0x8007003b might be caused by malware, an anti-virus on-demand check could help. Because Windows Defender is already built-in, you may use it to check for malware.

However, we advocate using a third-party antimalware program for Windows 10 for more sophisticated and accurate findings.

Dedicated antivirus software is updated on a regular basis and can defend you in real time from a variety of viruses and other dangers. The majority of them are simple to use, and the scanning procedure is similar to that of Windows Defender, so you won’t have any trouble adjusting to a new tool.

When the scan is complete, your antivirus program will show the findings and advise you on what to do next. If malware was the source of your problem, it should be resolved when it is removed.

Turn off anti-virus software for the time being.

If malware isn’t the problem, turn off your third-party anti-virus software for a while. It’s possible that your anti-virus software is interfering with the file transmission.

An anti-virus program may normally be turned off by right-clicking its system tray icon and choosing the deactivate option from the context menu.

Disable the tool for 15-30 minutes before attempting to copy the file again.

Turn off the Windows Firewall.

File transfers may potentially be hampered by the Windows Firewall. After all, it is a network firewall, thus turning it off might resolve issue 0x8007003b.

The Windows Firewall may be turned off in this manner.

  • To launch the app’s search box, press the Cortana button on the taskbar. In Cortana’s search bar, type firewall.

If your hard drive’s file system is FAT32, any file greater than 4 GB must be divided up before being copied to the PC. MP4 Tools, HJ-Divide, File Splitter, and Video Splitter are examples of applications that can split files.

You may also use the 7-Zip software to divide archived files. For further information on how to separate files, see this page.

Using the System File Checker to Scan Files
