Hi Rdeflem1,
From Windows 11 24H2, as a security enhancement, you cannot access SMB shared that has been configured to not require a password.
Since then, if your shared PC has no password, and other PCs using Windows 11 from 24H2, you cannot access.
To solve this, you have 2 choices: Set password for users / or Enable Insecure Guest Auth.
- Set password for users (recommended): then when you access shared files from other PCs, a prompt will appear, and all you have to do is simply enter your credential.
- Enable Insecure Guest Auth by running these commands in PowerShell (Run as administrator) then restart your computer:
Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force Set-SmbServerConfiguration -EnableInsecureGuestLogons $true -Force
If you have further information, please feel free to let me know.
