How to Fix: System Error 67 Has Occurred

The “System error 67 has occurred” problem occurs when Windows users try to run a network discovery scan or when they try to map a network drive from CMD or Powershell.

It turns out that one of the most common causes of this error is incorrect syntax. Some users use backslashes instead of forward slashes, forcing the terminal to treat them as offering options.

However, a faulty driver can also cause this error. Especially if you are using an older version of the driver that was released immediately after the first start of Windows 10. Other possible reasons are enabled policy for secure UNC paths or incorrectly configured IP NAT.

Check the command syntax

System error 67 can often be caused by a syntax error in the net map command. So make sure you enter the net map command correctly.

Make sure you enter the forward slash for the command on the right. The basic syntax for the net map command is net use * * IP address * sharename.

This way, there should be no left and right forward slashes around the command IP.
