What are the steps to fix QuickBooks Error 6000 103?

You can resolve QuickBooks Error 6000 103 by checking file configuration, network settings, and company file location. Follow the solutions below in order to identify and repair the cause.

Solution 1: Rename the .ND and .TLG files

QuickBooks creates .ND and .TLG files to manage network access and transaction logs. If these files become damaged, QuickBooks cannot connect to the company file.

Steps:

1. Open the folder that contains the QuickBooks company file.
2. Locate files with the same name as the company file but with extensions .ND and .TLG.
3. Right-click the .ND file and select Rename.
4. Add .OLD at the end of the file name.
5. Repeat the same step for the .TLG file.
6. Open QuickBooks Desktop and try opening the company file again.

QuickBooks automatically creates fresh configuration files.

Solution 2: Move the company file to a new folder

A damaged folder location may trigger QuickBooks Error 6000 103. Moving the company file helps verify whether the folder is causing the issue.

Steps:

1. Close QuickBooks Desktop.
2. Open the folder where the company file is stored.
3. Right-click the .QBW company file and select Copy.
4. Paste the file on the Windows Desktop.
5. Open QuickBooks while holding the Ctrl key.
6. Select Open or Restore an Existing Company File.
7. Browse to the Desktop location and open the file.

If the file opens successfully, the previous folder location caused the error.

Solution 3: Restore a backup company file

If the company file contains damage, restoring a backup copy may resolve the issue.

Steps:

1. Open QuickBooks Desktop.
2. Click File in the menu bar.
3. Select Open or Restore Company.
4. Choose Restore a Backup Copy.
5. Select Local Backup.
6. Browse to the backup file (.QBB).
7. Follow the prompts to restore the company file.

Solution 4: Check QuickBooks hosting settings

Incorrect hosting configuration may prevent workstations from accessing the company file.

Steps:

1. Open QuickBooks Desktop on each workstation.
2. Click File in the menu.
3. Select Utilities.
4. Check if the option shows Stop Hosting Multi-User Access.
5. If it appears, select it to disable hosting.
6. Ensure only the server computer hosts the company file.

Solution 5: Verify folder permissions

QuickBooks requires proper read and write access to the company file folder.

Steps:

1. Open the folder containing the company file.
2. Right-click the folder and select Properties.
3. Open the Security tab.
4. Select the user account running QuickBooks.
5. Enable Full Control permission.
6. Save the changes and reopen QuickBooks.
