A Windows 10 PC may give you the error message “You cannot connect to the shared folder because it is not secure” if you attempt to connect to it. For more information about resolving this issue, visit: https://go.microsoft.com/fwlink/?linkid=852747″, and proceed below to fix the issue. This share requires the obsolete SMB1 protocol, which is unsafe and can expose your system to attack.
It is possible that your system may be unable to connect to the file share due to the non-secure share (as SMBv1 and SMBv2) being configured incorrectly. It is also possible that your router firmware or OS is outdated.
After the Wannacry ransomware attack, users were instructed to disable SMBv1 on their system after it became known that many ransomware programs could access their systems. SMBv1 was deprecated by Microsoft after repeated attacks occurred. Microsoft eventually disabled SMBv1 on all systems as a result of a series of such attacks.
What causes the “This resource requires obsolete SMBv1 protocol” message?
- Servers and hosts enabled with SMBv1 may experience this problem.
- The problem may be caused by an outdated operating system on the host/client or outdated firmware on the router device.
