How to Fix QuickBooks Error 6143 – Top Solutions

Let’s walk you through multiple methods to fix this issue. Try them one by one to see which one works best for your situation.

1. Rename .ND and .TLG Files

These files help QuickBooks open a company file in a networked environment. If they’re corrupted, they can trigger Error 6143.

Steps:

  1. Open the folder where your company file is located.

  2. Look for files with the same name as your company file but with extensions .ND and .TLG.

  3. Rename them by adding .old at the end (e.g., CompanyName.qbw.nd → CompanyName.qbw.nd.old).

  4. Reopen QuickBooks and try accessing the file again.

2. Run QuickBooks File Doctor Tool (Using Tool Hub)

Intuit’s official QuickBooks Desktop Tool Hub contains the File Doctor Tool, which automatically diagnoses and fixes file-related issues.

Steps:

  1. Download and install QuickBooks Tool Hub from Intuit’s official site.

  2. Open Tool Hub and click Company File Issues.

  3. Click Run QuickBooks File Doctor.

  4. Browse and select your company file.

  5. Click Check your file and let the tool scan and fix the issue.

3. Restore a Backup File

If your current company file is severely corrupted, restoring a recent backup might be the easiest fix.

Steps:

  1. Open QuickBooks.

  2. Go to File → Open or Restore Company → Restore a backup copy.

  3. Choose Local Backup and follow the prompts to restore.

Make sure the backup file is recent to avoid data loss.

4. Verify and Rebuild Data

This built-in QuickBooks feature helps find and fix minor data issues.

Steps:

  1. Open QuickBooks.

  2. Go to File > Utilities > Verify Data.

  3. If it detects issues, go back to Utilities and click Rebuild Data.

Let QuickBooks finish the process and then try opening the company file again.

5. Create a New Windows User Profile

Sometimes, the issue can be OS-related. Creating a new Windows user profile with administrative rights may resolve the error.

Steps:

  1. Go to Control Panel > User Accounts.

  2. Create a new user with admin privileges.

  3. Log in using the new profile.
