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”.

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:
