How To Fix “0x8007003B” Error

When you set up a network with many Windows computers, it’s easy to share data with one another. However, things aren’t always as simple as that. Infrequent errors and hiccups are possible throughout that time.

When copying huge files over a network on a Windows PC, you may see an error notice similar to “Error 0x8007003B: An Unexpected Network Error Occurred.”

Method 1: Verify The Disk’s Format.

0x8007003B

Transferring huge files over a network can fail with the Error 0x8007003Bif the target drive is formatted in FAT32, which is a common scenario. This issue typically occurs while attempting to transfer a file that is larger than 4 GB.

Here are the procedures you need to do to verify the destination drive’s format.

Step 1: To open Windows File Explorer, just press the Windows key plus E.

Step 2: To access the drive’s settings, go to This PC, then right-click on the drive icon.

Step 31: Located under the “General” section, the file system of the target disc can be verified.

If the disc format is shown as NTFS, you can skip ahead to the other solutions. Files more than 4 GB in size will need to be compressed or an other destination disc will have to be chosen if the format indicates FAT32.

Method 2: Temporarily Turn Off Windows Firewall

File transfers over a network could be blocked inadvertently by Windows Defender Firewall. Multiple Microsoft forum members have reported success in resolving this issue by temporarily removing the Windows Defender Firewall. You may try it out, too.

Caution is advised. To compromise the safety of your computer, you should never turn off Windows Defender Firewall. Since this is a potentially dangerous situation, you should wait until the file transfer is complete before enabling the Windows Defender Firewall.

Step 1: To access the Run dialogue, use the Windows key plus R. Simply enter “control” into the Open field and hit the key.

Step 2: A drop-down menu in the window’s upper right corner lets you toggle between small and large icon views in the Control Panel. The next step is to open Windows Firewall using Defender.

Step 3: To enable or disable Windows Defender Firewall, select the corresponding option in the menu’s left-hand column. When prompted by User Access Control, choose Yes. It’s possible that you’ll need to log in as the administrator

Step 4: Access the Windows Firewall settings page and click the “Turn off Windows Firewall (not advised)” button. Select the OK button at the bottom to commit your changes.

If you’re using an external anti-virus programme on your PC, you may want to temporarily disable it until the transfer is complete. After that, you should turn on Windows’ firewall and any antivirus software.

Method 3: Initiate an SFC Scan

If some of your PC’s system files are missing or corrupted, you may also see the Error 0x8007003B notice. By scanning for problems with system files using SFC (System File Checker), you may identify and fix any problems that may exist. How to use it is explained below.

Step 1: Click the right mouse button on the Start menu, and then pick Windows Terminal (Admin).

A notice indicating whether or not the scan was successful will appear after the process has finished. In the event that it wasn’t, the utility will offer to try and recover and fix the data.

If the problem has resolved, try restarting the computer to see if it happens again.

Method 4: To Verify The Disk, Use The Disk Verification Utility

Unexpected network problems are generally the result of issues with the targeted hard drive. For Windows users, the Check Disk programme is a must, as it scans the disc for file system errors and repairs them automatically. How to use it is explained below.

Step 1: Use This PC as the starting point in File Explorer. Select the drive’s properties by right-clicking on it.

Step 2: Select the Check button that appears in the Error checking section of the Tools menu.

Step 3: To proceed, select “Scan and repair drive.”

If Windows finds any problems with your drive, it will attempt to resolve them automatically. The time required for this to complete will be proportional to the size of your hard drive.
