Running into a -6000 series error while trying to open your QuickBooks company file can feel like hitting a wall right when business needs to move forward. These errors typically signal issues with accessing the file, either due to file corruption, misconfigured settings, or network complications—whether you're using QuickBooks on a standalone desktop or in a multi-user setup.

Below is a table outlining the most common errors in this family and their typical causes:

Step 1: Update QuickBooks

Start by ensuring your QuickBooks software is up to date. Many common issues are resolved simply by installing the latest release.

Step 2: Use the QuickBooks Tool Hub

1. Install the Tool Hub

   • Close QuickBooks before starting.

   • Download the latest version (1.6.0.8) of the QuickBooks Tool Hub.

   • Save and run the installer (QuickBooksToolHub.exe).

   • Follow the setup instructions and launch the tool once installed.

2. Run QuickBooks File Doctor

   • In the Tool Hub, click on Company File Issues.

   • Select Run QuickBooks File Doctor.

   • If it doesn’t open automatically, search for it in your system and launch it manually.

   • Choose your company file, select "Check your file", and click Continue.

   • Enter your admin password and click Next.

If the problem continues, proceed with further troubleshooting below.

If You Access the File Locally

Solution 1: Rename .ND and .TLG Files

• Navigate to the folder containing your company file.

• Locate files with extensions .ND and .TLG (e.g., company.qbw.nd, company.qbw.tlg).

• Rename each file by adding .OLD to the end (e.g., company.qbw.nd.OLD).

• Reopen QuickBooks and try accessing the file again.

Solution 2: Open a Sample File

Open a QuickBooks sample file to determine if the issue is specific to your company file or affects all files. If the sample file opens without issue, your original file may be damaged.

Solution 3: Move the Company File to the Desktop

• Copy your company file from its current location to your desktop.

• Open QuickBooks while holding the Ctrl key.

• Choose "Open or restore an existing company" and select the file from the desktop.

Solution 4: Restore a Backup

Try restoring a recent backup of your company file. Make sure:

• Hosting is turned off (check under File > Utilities).

• The file path is less than 210 characters long.

• You are not navigating through too many nested folders.

Solution 5: Use Auto Data Recovery

If no backups are available or previous steps fail, you may try using QuickBooks’ Auto Data Recovery tool to recover recent transactions.

If You Access the File Over a Network

Solution 1: Check Hosting Settings

• On each computer, press F2 in QuickBooks to open Product Information.

• Under "Local Server Information", confirm that only the server computer has hosting enabled. All others should have hosting turned off.

Solution 2: Rename .ND and .TLG Files and Run Database Server Manager

• Rename the .ND and .TLG files as mentioned earlier.

• Open the QuickBooks Tool Hub and go to Network Issues.

• Launch the QuickBooks Database Server Manager and scan the folder containing your company file.

Solution 3: Open a Sample File from the Workstation

Try opening a sample company file on the same workstation. If it fails, you may need to repair or reinstall QuickBooks.

Solution 4: Move the Company File to Desktop

As with local access, moving the file to the desktop helps rule out folder path issues.

Solution 5: Close All QuickBooks Processes

On the server:

• Log in as Administrator.

• Open Task Manager (Ctrl + Shift + Esc).

• Under the Users tab, end all QuickBooks-related tasks (e.g., QBW32.EXE, qbupdate.exe, QBDBMgr.exe).

• Reopen QuickBooks and access the company file again.

Solution 6: Verify Folder Permissions

Ensure the folder where your company file is stored has full permissions for all users who need access.

Solution 7: Adjust Firewall and Antivirus Settings

Configure your firewall and antivirus software to allow QuickBooks to function properly. This includes opening required ports like 8019. Consult your antivirus provider for specific instructions, as Intuit does not support third-party security software.

If none of these steps resolve your issue, consider contacting a certified QuickBooks ProAdvisor or Intuit Support for further assistance.
