Win10 computer can't connect to Win2003 share because of SMB1
We had an incident today where a new laptop with Windows 10 Pro couldn't connect to the folder share on one of our servers. The server is an old Windows 2003 Standard. After some research, I found that SMB 1.0 is no longer included in the newer releases of Windows 10. Unfortunately for us, we're not ready to upgrade the server yet, so the fix had to be done on the client. Here's the solution I found on the web. This should be done on the Windows 10 computer. Press Windows key + R Type: optionalfeatures.exe, Enter Scroll down to SMB 1.0/CIFS File Sharing Support Check "SMB 1.0/CIFS Client" Click OK Restart the computer And done!
