Win10 20H2 fixes the issue.

Previously when 2004 broke smb1, I rolled back.

There was no registry change or any other modification made to the system.  After Win10 20H2 upgrade was installed via Windows Updates;  SMB1 worked as it did before the upgrade.

Thank you Microsoft.

    Sorry doesn't work for me. The only way that works for me is to recreate the mapped rive at each logging.

    You're right, they force users to migrate by using small "annoying annoyance" ...

    In a way they are right, but it might be better to give a positive incentive to migrate rather than push back like this.

    Sorry to hear that, unfortunately we don't have any more servers 2003/2008 servers with file shares for me to be able to troubleshoot and help with a solution. It must be something to do with the security vulnerabilities of SMBv1, MS is forcing everyone to upgrade. How i came across my fix was to disable SMBv1 on the client side and when trying to open the mapped drive i received the below error: ![](https://learn-attachment.microsoft.com/api/attachments/a93df548-d7c8-4d20-8d42-6e44b26cefe8?platform=QnA

    • This is what led me to enabling SMBv2 on server side. So id suggest upgrading to server 2012 r2 or higher and enabling SMBv2/3.
