This policy setting allows you to manage whether the Windows Remote Management (WinRM) client will not use Kerberos authentication directly. If you enable this policy setting, the Windows Remote Management (WinRM) client will not use Kerberos authentication directly. Kerberos may still be used if the WinRM client is using the Negotiate authentication and Kerberos is selected. If you disable or do not configure this policy setting, the WinRM client will use the Kerberos authentication directly. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Client!Disallow Kerberos authentication (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WinRM\Client!AllowKerberos
