The error code 0x0000042E translates to 1070 in decimal and is related to the DHCP (Dynamic Host Configuration Protocol) service on Windows systems. It signifies an issue where the DHCP service was unable to access the path specified for its audit log. Here’s how to troubleshoot this error:

Understanding the Error:

The DHCP service plays a crucial role in automatically assigning IP addresses to devices on a network. The audit log tracks the service’s activities, but when this error occurs, the log cannot be accessed or written to due to a path access issue.

Troubleshooting Steps:

1. Verify DHCP Service Permissions:

   • The DHCP service requires specific permissions to access its log file. Ensure the account the service runs under has read/write permissions for the designated log file location.

     • Opening Services Management Console: Search for “Services.msc” in the Start menu or search bar.
     • Locate DHCP Service: Find “DHCP Server” in the list of services.
     • Right-click Properties: Right-click on “DHCP Server” and select “Properties.”
     • Log On Tab: Navigate to the “Log On” tab.
     • Verify Account Permissions: Check the account listed under “This service logs on as”. You might need to consult program documentation or seek IT support to understand the appropriate permissions required for the DHCP service on your system.

2. Check Log File Path:

   • The error message might indicate a specific path issue with the audit log.
     • Event Viewer (Informational): Open Event Viewer (search for “eventvwr.msc”) and look for entries related to the DHCP service around the time the error occurred. The event details might mention the problematic path.
     • Service Properties – Recovery Tab (Optional): In the DHCP service properties window (from step 1), navigate to the “Recovery” tab (if available). The “First failure,” “Second failure,” and “Subsequent failures” actions might specify a recovery program or script location, which could also provide clues about the log file path.

3. Ensure Path Accessibility:

   • Once you have the suspected log file path, verify that the location exists and is accessible by the account the DHCP service uses. You might need administrative privileges to modify folder permissions if necessary.

4. Check Disk Errors:

   • In rare cases, disk errors might prevent the DHCP service from accessing its log file. Running a disk check can help identify and potentially fix these issues:
     • Open Command Prompt (Admin).
     • Type chkdsk /f C: (replace C: with the drive letter where the log file is located) and press Enter. This will scan and fix errors on the specified drive (make sure to back up important data before running chkdsk /f).

5. Update DHCP Service (if applicable):

   • In some instances, outdated versions of the DHCP service might have bugs contributing to log access issues. Check for updates following the recommendations for your specific Windows version.

Additional Tips:

• Consider creating a system restore point before making significant system changes (e.g., modifying service permissions). This allows you to restore your system to a known good state if issues arise.
• If none of these steps resolve the issue and the error disrupts network functionality significantly, consider seeking help from a qualified IT professional. They can analyze your system logs, investigate the DHCP service configuration, and provide tailored solutions to ensure proper network function and audit logging.

Important Note: Modifying service permissions and file system access can have security implications. It’s crucial to understand the purpose of the DHCP service and its log files before granting access. If unsure, consulting a qualified IT professional is recommended to avoid unintended consequences.
