How to fix Error 1923 on Windows 11

Why This Error Happens

Error 1923 typically occurs when a Windows service fails to install or start due to insufficient account permissions, particularly when the service is tied to a specific user account that lacks the “Log on as a service” right. In the context of “Not all object UUIDs could be exported to the specified entry,” this points to a breakdown in the RPC (Remote Procedure Call) registration process, often caused by corrupted registry entries or a mismatch between the service’s security context and Active Directory/local security policy. Third-party antivirus or Group Policy restrictions can also block the UUID export process, preventing the service from registering correctly with the Service Control Manager.

Step-by-Step Resolution Guide

Step 1: Verify Account Permissions and Service Logon Rights

  • Open the Local Security Policy editor by typing secpol.msc into the Windows 11 search bar.
  • Navigate to Security Settings > Local Policies > User Rights Assignment.
  • Locate “Log on as a service” and ensure the account attempting to run the affected application/service is listed.
  • If missing, click Add User or Group, input the account name, and apply the changes.

Step 2: Repair Corrupted Registry Entries via System File Checker

  • Open Command Prompt as Administrator (right-click Start Menu > Terminal (Admin)).
  • Run the System File Checker to scan for corrupted system files: sfc /scannow
  • Once complete, run the Deployment Image Servicing and Management tool to repair the Windows image: DISM /Online /Cleanup-Image /RestoreHealth
  • Restart the machine to apply repairs.

Step 3: Re-register the Service Using Correct Credentials

  • Open Services (services.msc) and locate the specific application service causing the 1923 error.
  • Right-click the service, select Properties, and go to the Log On tab.
  • Switch the “Log on as” setting from Local System account to This account, and manually input a valid Administrator username and password.
  • Click Apply, then attempt to start the service manually to see if the UUID export completes.

Step 4: Check Group Policy and Firewall Restrictions

  • Open the Group Policy Editor (gpedit.msc) and check under Computer Configuration > Windows Settings > Security Settings for any restrictive RPC policies.
  • Temporarily disable third-party antivirus/firewall software to rule out interference with RPC communication.
  • Retry the installation or service start-up process to see if the UUID export error persists.

Alternative or Verification Steps

  • Verification: Open Event Viewer (eventvwr.msc), navigate to Windows Logs > System, and filter for Event ID 1923 to confirm the specific service no longer throws the error upon restart.
  • Alternative: If the error persists, use the built-in sc.exe command in Command Prompt (Admin) to manually delete and reconfigure the specific service entry: sc delete [ServiceName] followed by a clean reinstall of the software package.
