You are getting the message “Cannot connect to File Share. This share requires an outdated SMB1 protocol” when you try to access a remote file share? If yes, the problem is that the remote server you are trying to connect to is using an outdated SMB1 protocol for the share (Windows 10 uses SMB2 or higher by default).
However, SMB1 is included in the optional Windows features for users like you, who can enable it if needed. Follow these guidelines and you should be able to connect to a remote file-sharing server without any problems.
What is causing the “This resource requires obsolete SMB1 protocol” message?
The reason is that SMBv1 is out of date. Microsoft strongly recommends that consumers use SMB2 or a higher protocol.
In Windows 10 Fall Creators Update and later versions, the Server Message Block Version 1 (SMBv1) network protocol is no longer installed by default. Beginning in 2007, it will be replaced by SMBv2 and higher protocols.
This is why I got an error when accessing the share from a Windows 10 computer. Also, if you install Windows 10 Enterprise 1903, it no longer includes the SMBv1 client, but SMBv1 can still be reinstalled in all editions of Windows 10.
How to eliminate the “This resource requires legacy SMB1 protocol” message?
Update the operating system
- Manually update the Windows (or operating system) host system/client and see if the secure connection issue has been resolved.
- If not, update the router firmware and check if the file-sharing issue has been resolved.
Turn on SMBv1 and SMBv2 protocols
- Click on Windows, type: Control Panel, then select Control Panel.
- Then click on Programs and open Turn Windows features on or off.
- Then disable the SMB 1.0/CIFS File Sharing Support and SMB Direct options on the server/host computer.
- If this option is not available, enable the SMBv1 features on the client computer.
- Now apply the changes and see if the secure connection issue is resolved.
