The Allow unencrypted traffic machine setting should be configured correctly for the WinRM client. This policy setting allows you to manage whether the Windows Remote Management (WinRM) client sends and receives unencrypted messages over the network. If you enable this policy setting, the WinRM client sends and receives unencrypted messages over the network. If you disable or do not configure this policy setting, the WinRM client sends or receives only encrypted messages over the network. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Client\Allow unencrypted traffic (2) KEY: HKLM\Software\Policies\Microsoft\Windows\WinRM\Client\AllowUnencryptedTraffic
