2. Run QuickBooks File Doctor 

QuickBooks File Doctor verifies company files for potential damage or network connectivity issues and performs quick repairs if any problems are found.

Note: Download and install QuickBooks Tool Hub in the latest version (1.6.0.8). You must close QuickBooks to use Tool Hub. For the best experience, we recommend using Tool Hub on Windows 11 (64-bit).

Case 1: When you open the file locally 

If you open the company file on the local computer and see multiple 6000 series in QuickBooks, follow the steps below. For professional help, connect with us at 866-500-0076.

1. Rename the .ND and .TLG files

The .ND and .TLG are the configuration files for QuickBooks that allow the program to access a company file in a network or multi-user environment.

If these files are damaged, you will see the following errors when trying to open the file. Renaming these files will replace them with the new files; you won’t lose any QuickBooks data. QuickBooks will create these files again when scanned with QuickBooks Database Server Manager and when you open the company file. 

  • Open the folder where your company file is saved. 
  • Look for the files with the same name as your company file but with the extensions .ND and .TLG
    • company_file.qbw.nd
    • company_file.qbw.tlg
  • Right-click on each file and select Rename. Add .OLD at the end of each file name, such as: 
    • company_file.qbw.nd.OLD

Launch QuickBooks Desktop and try to sign into the company file again. If the same issue occurs, go to Solution 2. 

2. Open a sample company file

When opening a sample company file, you can check whether the issue is with your company file or QuickBooks. If the sample file doesn’t open and shows an error, your QuickBooks installation may be damaged. You’ll need to repair the installation.

  • In the No Company Open window, select Open a Sample File and choose any file from the list.

  • If the sample file opens, proceed to solution 3. If it shows the same error, repair your QuickBooks installation files.

Here’s how to repair the QuickBooks installation

  • Launch the QuickBooks Tool Hub. 
  • Go to Installation Issues in the left menu bar. 
  • Hit on the QuickBooks Install Diagnostic Tool. Let the tool run until it finishes; usually, it takes up to 20 minutes.

  • Also, make sure QuickBooks is up-to-date to the latest release to ensure you use the most recent fixes and security updates.

3. Copy the QuickBooks file to the Desktop

When you open the file after copying it to your desktop, it will automatically run a quick test to check for issues with the company file location.

  1. If the company file opens from the desktop, it shows the potential damage to the location where you saved it. 
  2. The file might be saved in too many folders, exceeding the file system path limit. 
  3. If the company file doesn’t open after changing its location, it may be damaged. 
  • Open the folder where your company file is located. 
  • Look for the file with the .QBW extension. 
  • Right-click on the file and select Copy. Go to your Desktop and right-click anywhere on the desktop. Then, select Paste.
  • Press and hold down the Ctrl key and open QuickBooks. This will redirect you to the No Company Open window. 
  • Click on Open or restore an existing company. Go to your desktop and look for the company file to open it. 

If you get any of the QuickBooks error 6000, go to Solution 3.

4. Restore a backup

In QuickBooks, restore a backup copy of your company file to see if the problem is with the current company file.

If you see an error while restoring the backup, follow these steps: 

1. Check the computer that isn’t hosting the file.

  • Open your company file. 
  • Go to File and select Utilities.
Stop Hosting Multi-User Access
  • If you haven’t selected Stop Hosting Multi-User Access:
    • Click on Stop Hosting Multi-User Access.
    • In Stop hosting multi-user access, click Yes
    • In the Company file, the window must be closed, and click Yes

2. Make sure the company file path isn’t longer than 210 characters.

  • Locate the company file. 
  • Copy the location of your company file. 
  • Paste it into the notepad and count the characters and the spaces. 
  • For example: C: Documents and SettingsAll UsersDocumentsIntuitQuickBooksSample Company FilesQuickBooks 2018Sample_company_file.qbw is 125 characters.

3. When done, try to restore the company file again.

If you still get QuickBooks error 6000, go to Solution 5.

5. Use Auto Data Recovery to restore your backup

If you have lost the company file data or it is damaged, it is suggested to recover the lost data using the QuickBooks Auto Data Recovery tool

Case 2: When you open the file over a network 

Opening the hosted file on a network workstation and running QuickBooks File Doctor didn’t help? See the solutions below to resolve hosting issues and fix error code 6000 in QuickBooks.

It is recommended to use only one computer or server to host your company’s files. 

  • Press F2 to open the Product Information window.

  • Look for Local Server Information. Hosting should be turned off on the workstations. 

2. Rename the .ND and .TLG files, and run the Database Server Manager from the QuickBooks Tools Hub

The .ND and .TLG files are part of your QuickBooks files. These are configuration files that allow QuickBooks to access a company file in a network or multi-user environment.

If these files are damaged, you’ll see these errors when you open your QuickBooks files. When you rename these files, you won’t lose any QuickBooks data. QuickBooks creates these files again when you scan with the QuickBooks Database Server Manager and when you open your company file.

a. Rename the .ND and .TLG file

Refer to Solution 1 under Case 1 to rename the .ND and .TLG file components in QuickBooks Desktop to resolve the company file error 6000. 

b. Run the QuickBooks Database Server Manager

The QuickBooks Database Server Manager hosts the QuickBooks company files. Restart the QB Database Server Manager and scan the QuickBooks files after renaming the .ND and .TLG files.

If you have already installed QuickBooks Database Server Manager, run the tool from the QuickBooks Tool Hub. 

  • Launch the QuickBooks Tool Hub. 
  • Click on Network Issues in the left menu bar. 
  • Hit on QuickBooks Database Server Manager. Install the Server Manager if you haven’t already. 
QuickBooks Database Server Manger
  • Select Start Scan in the QuickBooks Database Server Manager only if you see your company file. If you don’t, click Browse, locate to the company file location, and then select Start Scan
  • Open QuickBooks Desktop and try to sign in to your company file. If you still get the same issue, go to the next solution. 

3. Open a sample company file from a workstation

Refer to Solution 2 under Case 1 for the steps to test whether the issue is with the company file or the location. 

4. Copy the QuickBooks file to the Desktop

To determine whether the issue is related to the company file or its location, try copying the QuickBooks file to your desktop. This can help isolate any problems caused by the file’s current location.

For the steps, refer to Solution 3 under Case 1.

5. Close all QuickBooks processes

Multiple QuickBooks processes running in the background may degrade network connectivity to the company file and the server, resulting in Quickbooks 6000 series errors. End the processes to refresh the connection using the steps: 

  • Sign in to your server computer as an Administrator.
  • Press Ctrl+Shift+Esc to launch the Task Manager.
  • Click on Show processes for all users, then select Users.
  • Choose each QuickBooks process (QBW32.EXE, qbupdate.exe, and QBDBMgr.exe) and select End Task.
  • Try opening the company file in multi-user mode again. 

If you still encounter an error, go to Solution 6. 

6. Check the folder permission manually

To access folders in multi-user mode, ensure the correct Windows permissions are set. Each version of QuickBooks has specific components that must be updated for multi-user functionality. This will ensure you have the right set of permissions when opening the company file on a workstation or server, resolving QuickBooks error code 6000. 

7. Configure firewall ports and Anti-Virus Software

Windows Firewall may block QuickBooks connections, leading to QuickBooks error 6000. To resolve this, configure the Windows Firewall to allow QuickBooks Desktop by adding exceptions for its specific files, folders, and ports. This ensures proper communication and prevents the firewall or antivirus software from interrupting access to your company files.
