PSSmb contains commands for getting the status of SMB client and server components, and enabling and disabling the different versions installed on local and remote computers.

Due to recent vulnerabilities like EternalBlue that was used by the ransomware WannaCry and the wiper PetyaWrap, it is now recommended to disable both the client and server components of SMB version 1 entirely, and can be done with Group Policy through the Disable-SmbByGpo command.

It is important to point out that SMB versions 2 and 3 use the same stack, so enabling or disabling one of these versions will cause the same thing to happen to the other version.

When using the Enable-Smb or Disable-Smb commands, it is recommended to use the Restart parameter to cause the computer to immediately reboot after the changes have been made. This is required for the changes to take effect.
