This policy setting allows you to manage whether the Windows Remote Management (WinRM) client uses CredSSP authentication. If you enable this policy setting, the WinRM client will use CredSSP authentication. If you disable or do not configure this policy setting, then the WinRM client will not use CredSSP authentication. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Client!Allow CredSSP authentication (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WinRM\Client!AllowCredSSP
