There are several ways to troubleshoot and fix QuickBooks Error 6143. Below are step-by-step methods to resolve the issue.

1. Solution 1: Use QuickBooks File Doctor

QuickBooks File Doctor is a built-in tool that automatically detects and repairs file corruption. It can fix issues related to your company file, including Error 6143.

Steps to use QuickBooks File Doctor:

Download the QuickBooks Tool Hub from the official Intuit website if you haven’t installed it yet.
Open the Tool Hub and click on Company File Issues.
Select Run QuickBooks File Doctor.
When the File Doctor tool launches, choose your company file from the dropdown menu. If you don’t see your file, click Browse and search for it.
Select Check Your File and then click Continue.
Enter your QuickBooks admin password and click Next.
The tool will scan and attempt to repair the company file.

After the scan, try reopening your company file. If the error persists, proceed to the next solution or call 1-855-200-0590 for immediate support.

2. Solution 2: Restore a Backup of Your Company File

If the current company file is corrupted, you can restore a previously saved backup to resolve the error.

Steps to restore a backup:

Open QuickBooks and go to the File menu.
Select Open or Restore Company.
Choose Restore a backup copy and click Next.
Select Local Backup and click Next.
Browse for your backup file and click Open.

3. Solution 3: Rename the .ND and .TLG Files

The .ND (Network Descriptor) and .TLG (Transaction Log) files play a crucial role in accessing the company file over the network. If these files are damaged or corrupted, they can trigger QuickBooks Error 6143. Renaming them will not harm your data, as QuickBooks will automatically recreate these files when you open the company file.

Steps to rename .ND and .TLG files:

Navigate to the folder containing your QuickBooks company file.
Look for files with the same name as your company file but with .ND and .TLG extensions.
Right-click on the .ND file and select Rename. Add .OLD to the end of the filename (e.g., CompanyFile.ND.OLD).
Repeat the same process for the .TLG file.
After renaming the files, open QuickBooks and try accessing your company file.

If you are still facing the error after renaming these files, reach out to QuickBooks support at 1-855-200-0590 for professional help.

Open QuickBooks and go to the Help menu.
Select Update QuickBooks Desktop.
Click Update Now and then Get Updates.
After the update is complete, restart QuickBooks.
