Table of Contents

This guide provides comprehensive methods to diagnose and resolve SCECLI 1202 events encountered in Windows Server environments. These events signal issues within the Security Configuration Client-Side Extension, often hindering the proper application of security policies. Understanding the root cause of these errors is crucial for maintaining a secure and efficiently managed server infrastructure.

Summary

The initial step in addressing SCECLI 1202 events involves pinpointing the specific Win32 error code associated with the event. This error code is paramount as it elucidates the nature of the failure triggering the SCECLI 1202 event. Within the event’s Description field, the error code is clearly presented. For instance, an error code of 0x534 is exemplified below. The text immediately following the numerical code offers a textual description of the error. Once the error code is identified, locate the corresponding section within this guide and meticulously follow the outlined troubleshooting procedures.

0x534: No mapping between account names and security IDs was done.

or

0x6fc: The trust relationship between the primary domain and the trusted domain failed.

Error code 0x534: No mapping between account names and security IDs was done

Error code 0x534

Error code 0x534 signifies a failure in resolving a security account name to its corresponding Security Identifier (SID). This issue typically arises due to either a typographical error in the account name or the deletion of the account after its inclusion in a security policy setting. Frequently, this error manifests within the User Rights or Restricted Groups sections of the security policy configuration. Furthermore, it can occur in scenarios where the account resides across a domain trust and that trust relationship subsequently becomes broken or compromised.

To effectively troubleshoot error code 0x534, adhere to these systematic steps:

  1. Identify the Problematic Account: To pinpoint the account causing the failure, enable debug logging for the Security Configuration client-side extension. This enhanced logging will provide detailed information about the error.

    a. Open the Registry Editor. You can do this by typing regedit in the Run dialog box (Win + R) and pressing Enter.

    b. Navigate to the following registry subkey using the left-hand pane:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}

    c. On the Edit menu at the top of the Registry Editor window, select New, and then click DWORD (32-bit) Value.

    d. Name the new value as ExtensionDebugLevel.

    e. Double-click ExtensionDebugLevel, and in the Value data field, enter 2. This sets the debug level to enable detailed logging. Click OK.

    f. Close Registry Editor.

  2. Refresh Policy Settings: Force a refresh of the Group Policy settings to reproduce the error and generate the necessary log files. Open Command Prompt as an administrator and execute the following command:

gpupdate /target:computer /force

This command initiates a forceful update of computer policy settings. Upon completion, it creates a log file named Winlogon.log located in the %SYSTEMROOT%\Security\Logs directory.

  1. Locate the Problem Account: Analyze the Winlogon.log file to identify the specific account causing the resolution failure. In Command Prompt, use the find command to search for relevant entries:
find /i "cannot find" %SYSTEMROOT%\security\logs\winlogon.log

The output from this command will highlight lines containing “Cannot find”, typically followed by the name of the problematic account. For example, you might see an output like “Cannot find MichaelPeltier”. This indicates that the user account ‘MichaelPeltier’ is either non-existent in the domain or has a spelling discrepancy, such as ‘MichellePeltier’.

Investigate the reasons for account resolution failure. Consider potential typographical errors in the account name, the possibility of a deleted account, incorrect Group Policy application to the computer, or issues with the domain trust relationship.

  1. Identify the Problem Policy and Setting: Once you confirm that the account needs removal from the policy, determine the specific Group Policy Object (GPO) and setting containing the unresolved account. Run the following command in Command Prompt on the affected computer:
c:\>find /i "account name" %SYSTEMROOT%\security\templates\policies\gpt*.*

Replace "account name" with the actual account name identified in the previous step (e.g., “MichaelPeltier”).

For example:

c:\>find /i "MichaelPeltier" %SYSTEMROOT%\security\templates\policies\gpt*.*
---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00000.DOM

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00001.INF

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00002.INF
SeInteractiveLogonRight = TsInternetUser,*S-1-5-32-549,*S-1-5-32-550,MichaelPeltier,*S-1-5-32-551,*S-1-5-32-544,*S-1-5-32-548

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00003.DOM

This output indicates that GPT00002.inf is the cached security template from the relevant GPO, and the problematic setting is SeInteractiveLogonRight. The user-friendly display name for SeInteractiveLogonRight is “Logon locally”.

To understand the mapping between these constants (like SeInteractiveLogonRight) and their display names (like “Logon locally”), refer to the User Rights Assignment documentation.

  1. Determine the GPO: To identify the GPO associated with the cached security template found in step 4, search within the template file for the line starting with GPOPath=. For instance, you may find:
GPOPath={6AC1786C-016F-11D2-945F-00C04FB984F9}\\MACHINE

{6AC1786C-016F-11D2-945F-00C04FB984F9} represents the Globally Unique Identifier (GUID) of the GPO.

  1. Find the GPO Friendly Name: To obtain the user-friendly name of the GPO using its GUID, employ the Get-GPO -Guid PowerShell cmdlet. This command should be executed on a Domain Controller (DC) or a server with Active Directory Remote Server Administrator Tools (RSAT) installed.
Get-GPO -Guid 6AC1786C-016F-11D2-945F-00C04FB984F9

The output will display the GPO’s properties, including the DisplayName, which is the friendly name:

DisplayName : Default Domain Controllers Policy
DomainName : contoso.com
Owner : CONTOSO\Domain Admins

With the problem account, setting, and GPO identified, you can now resolve the issue by either removing or correcting the problematic entry within the GPO settings.

Error code 0x2: The system cannot find the file specified

Error code 0x2

Similar to error codes 0x534 and 0x6fc, error code 0x2 typically stems from an unresolvable account name. When 0x2 errors occur, it often indicates that the problematic account is specified within a Restricted Groups policy setting. This error highlights a situation where the system is attempting to apply a policy related to restricted groups, but it cannot locate a file or resource associated with a specified account within that policy.

To troubleshoot error code 0x2, follow these outlined steps:

  1. Determine the Failing Service or Object: Enable debug logging for the Security Configuration client-side extension to gain detailed insights into the error.

a. Launch Registry Editor (regedit).

b. Locate and select the registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}

c. From the Edit menu, select New -> DWORD (32-bit) Value.

d. Name it ExtensionDebugLevel.

e. Modify the ExtensionDebugLevel value data to 2.

f. Exit Registry Editor.

  1. Refresh Policy Settings: Force a Group Policy update to reproduce the error. Open Command Prompt as administrator and run:
gpupdate /target:computer /force

This generates the Winlogon.log file in %SYSTEMROOT%\Security\Logs.

  1. Identify the Problem Account: Analyze Winlogon.log for “cannot find” entries to identify the account causing the error.
find /i "cannot find" %SYSTEMROOT%\security\logs\winlogon.log

The output will highlight lines indicating accounts that could not be found, for example, “Cannot find MichaelPeltier”. Investigate if the account is misspelled, deleted, or if there is a domain trust issue preventing resolution.

  1. Locate the Problem Policy and Setting: Determine the GPO and setting containing the unresolved account. Execute the following command in Command Prompt:
c:\>find /i "account name" %SYSTEMROOT%\security\templates\policies\gpt*.*

Replace "account name" with the identified problematic account.

Example output:

c:\>find /i "MichaelPeltier" %SYSTEMROOT%\security\templates\policies\gpt*.*
---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00000.DOM

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00001.INF

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00002.INF
SeInteractiveLogonRight = TsInternetUser,*S-1-5-32-549,*S-1-5-32-550,JohnDough,*S-1-5-32-551,*S-1-5-32-544,*S-1-5-32-548

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00003.DOM

This identifies GPT00002.inf and the setting SeInteractiveLogonRight.

  1. Determine the GPO: Search GPT00002.inf for GPOPath= to find the GPO GUID. For example:
GPOPath={6AC1786C-016F-11D2-945F-00C04FB984F9}\\MACHINE
  1. Find the GPO Friendly Name: Use Get-GPO -Guid in PowerShell to get the GPO’s display name:
Get-GPO -Guid 6AC1786C-016F-11D2-945F-00C04FB984F9

Example output:

DisplayName : Default Domain Controllers Policy
DomainName : contoso.com
Owner : CONTOSO\Domain Admins

After identifying the problem account, setting, and GPO, resolve the issue by removing or correcting the account entry within the Restricted Groups section of the security policy.

Error code 0x5: Access denied

Error code 0x5

Error code 0x5, “Access denied,” commonly arises when the system lacks the necessary permissions to modify the Access Control List (ACL) of a service. This situation can occur if an administrator defines service permissions within a policy but inadvertently fails to grant the System account Full Control permissions. The System account is crucial for the Security Configuration Client-Side Extension to properly apply security settings to services.

To troubleshoot error code 0x5, follow these steps:

  1. Identify the Failing Service or Object: Enable debug logging for the Security Configuration client-side extension to obtain detailed error information.

a. Open Registry Editor (regedit).

b. Navigate to the registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}

c. Add a new DWORD (32-bit) Value: Edit -> New -> DWORD (32-bit) Value.

d. Name it ExtensionDebugLevel.

e. Set the ExtensionDebugLevel value data to 2.

f. Close Registry Editor.

  1. Refresh Policy Settings: Force a Group Policy update to reproduce the error and generate logs. Open Command Prompt as administrator and run:
gpupdate /target:computer /force

This will create the Winlogon.log file in %SYSTEMROOT%\Security\Logs.

  1. Identify the Problematic Service: Analyze Winlogon.log for “error opening” entries to identify the service with permission issues.
find /i "error opening" %SYSTEMROOT%\security\logs\winlogon.log

The output may identify the service, for example, “Error opening Dnscache”. “DnsCache” is the short name for the DNS Client service.

  1. Find the Policy Modifying Service Permissions: Determine which policy attempts to modify the service permissions. Execute this command in Command Prompt:
find /i "service" %SYSTEMROOT%\security\templates\policies\gpt*.*

Example command and output:

d:\>find /i "dnscache" %windir%\security\templates\policies\gpt*.*

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00000.DOM

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00001.INF

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00002.INF
Dnscache,3,"D:AR(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;LA)"

---------- D:\WINNT\SECURITY\TEMPLATES\POLICIES\GPT00003.DOM
  1. Determine the GPO: Search the identified template file (e.g., GPT00002.inf) for GPOPath= to find the GPO GUID:
GPOPath={6AC1786C-016F-11D2-945F-00C04FB984F9}\\MACHINE
  1. Find the GPO Friendly Name: Use Get-GPO -Guid in PowerShell to get the GPO’s display name:
 Get-GPO -Guid 6AC1786C-016F-11D2-945F-00C04FB984F9

Example output:

 DisplayName : Default Domain Controllers Policy
 DomainName : contoso.com
 Owner : CONTOSO\Domain Admins

Having identified the service with misconfigured permissions and the responsible GPO, rectify the issue by examining the System Services section of the security policy. Ensure that the System account is granted Full Control permissions for the identified service.
