Hello
Thank you for posting in Microsoft Community forum.
The SceCli 1202 event on your Windows Server 2016 indicates that the security policy was propagated with a warning. The error code 0xd suggests invalid data.
Here are some steps to troubleshoot this issue:
Determine the account causing the failure: Enable debug logging for the Security Configuration client-side extension. You can do this by editing the registry. Locate and select the following registry subkey: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}. Add the following registry value: Value name: ExtensionDebugLevel, Data type: DWORD, Value data: 2.
Refresh the policy settings to reproduce the failure: Type the following command at the command prompt, and then press ENTER: secedit /refreshpolicy machine_policy /enforce. This command creates a file named Winlogon.log in the %SYSTEMROOT%\Security\Logs folder.
Find the problem account: Type the following command at the command prompt, and then press ENTER: find /i "cannot find" %SYSTEMROOT%\security\logs\winlogon.log. The Find output identifies the problem account names.
Determine why this account can’t be resolved: To determine which setting contains the unresolved account, type the following command at the command prompt on the computer that’s producing the SCECLI 1202 event, and then press ENTER: c:\>find /i "account name" %SYSTEMROOT%\security\templates\policies\gpt*.*.
Please note that modifying the registry can cause serious problems if not done correctly. It’s recommended to back up the registry before you modify it.
