Issue: How to Fix Windows 10 Error Code 0x8007003B "An unexpected network error occurred"?

Hello. I want to report a problem, which is consistently happening on the Anniversary Update (1607) of Windows 10. When I create a folder on a share on Windows Server 2012 R2 Essentials, File Explorer gets stuck for about a minute and then displays an error message that reads as follows: “An unexpected error is keeping you from renaming the folder […] Error 0x8007003B: An unexpected network error occurred”. Please help me fix this issue!

Solved Answer

Users started reporting Error Code 0x8007003B error back in 2016 when Windows 10 Pro Version 1607[1] Build 14393.x (the August 2016 Anniversary Edition) was released. 

Research revealed that any type of Windows 10-1607 (virtual machine or physical, with different motherboard/NIC[2] manufacturers) running Windows Server 2012 R2 Essentials in a virtualised environment could, and usually does, encounter this error when trying to create or rename a folder.

The process of such task is extended obviously from the first click and eventually freezes handing File Explorer and ending up with an error message:

Error 0x8007003B: An unexpected network error occurred.

Several people pointed out that the error causes Outlook to stop working as well.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
