Disable SMB Signing on Windows 11 from PowerShell
To turn off the SMB Signing feature on Windows 11 using PowerShell, follow these instructions:
Open Start.
Search for PowerShell (or Terminal), right-click the top result, and select Run as administrator.
Type the following command to disable SMB Signing and press Enter:
Set-SmbClientConfiguration -RequireSecuritySignature $false
PowerShell disable SMB signing
Type “Y” and press Enter to confirm the changes.
(Optional) To verify the SMB Signing status on Windows 11, you can run the following command:
Get-SmbClientConfiguration | Format-List EnableSecuritySignature,RequireSecuritySignature
Restart your computer.
Once these steps are completed, you should be able to access and browse your file server on the network without encountering errors.
If you need to revert this change later, just follow the same instructions, but execute the command Set-SmbClientConfiguration -RequireSecuritySignature $true in step 3.
