Using PowerShell or Command Prompt for SMBv2 troubleshooting

To troubleshoot SMBv2 issues on Windows 11/10 systems, you can use either PowerShell or Command Prompt. Both tools provide effective ways to enable or disable SMB versions.

Using PowerShell, open the Start menu and search for “PowerShell.” Right-click on the Windows PowerShell result and select “Run as administrator.” To enable SMBv2, enter the command “Set-SmbServerConfiguration -EnableSMB2Protocol $true” and press Enter. Similarly, to disable SMBv2, use the command “Set-SmbServerConfiguration -EnableSMB2Protocol $false“.

Alternatively, you can use Command Prompt by pressing Win + X to open the Power User Menu and selecting “Command Prompt (Admin).” To enable SMBv2, type “sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi” and hit Enter. For disabling SMBv2, use the command “sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi“.

By using either PowerShell or Command Prompt, you can easily enable or disable SMBv2 to troubleshoot any related issues on your Windows 11/10 system.

SMBv2 is a significant improvement over its predecessor, offering enhanced security features and better performance.

Resolving “Your system requires SMB2 or higher” error

To resolve the “Your system requires SMB2 or higher” error, follow these steps:

1. Press the Windows key + X on your keyboard to open the Power User Menu.
2. Select “Command Prompt (Admin)” to open an elevated command prompt.
3. In the command prompt, type “sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi” and press Enter.
4. Restart your computer for the changes to take effect.

By disabling SMBv1 and enabling SMBv2 or higher, you ensure better security and compatibility with modern devices and applications. SMBv2 and SMBv3 are more secure versions of the Server Message Block protocol, offering improved file sharing and network communication.

Note that SMBv1 is an older technology that is susceptible to exploits and should be disabled whenever possible. Enabling SMBv2 or higher is recommended for a safer and more reliable network environment.
