Solutions to Fix QuickBooks Error Code 6000 Series

The 6000 series covers several different errors, so the appropriate fix depends on the error code you receive.

Solution 1: Update QuickBooks Desktop to the Latest Release

Start by updating QuickBooks Desktop to the latest release.

  1. The first thing you need to do is open QuickBooks Desktop.
  2. After that, navigate to Help > Update QuickBooks Desktop.
  3. Click on Update Now, then Get Updates.
    Get Updates in QuickBooks
  4. Restart QuickBooks Desktop after the update finishes and try opening the company file again.

This solution is one of the basic troubleshooting steps for the QuickBooks 6000 error. Further ahead, we will discuss the rest of the solutions.

Solution 2: Rename the “.ND” and “.TLG” Files

QuickBooks uses support files such as .TLG, .ND, and .DSN alongside the company file. If one of these files is damaged, renaming it allows QuickBooks to recreate the file.

  1. Try to open the folder that contains your company file.
  2. Look for files with the same name as your QuickBooks file but with extensions .TLG, .ND, and/or .DSN.
  3. Then, right-click each file and select Rename and add .OLD to each file.
    rename .ND and .TLG files

Note: QuickBooks automatically recreates these files.

If the issue persists, move to the next solution.

Solution 3: Run QuickBooks File Doctor

QuickBooks File Doctor checks the company file and network for issues that may prevent QuickBooks from opening the file.

First, install QuickBooks Tool Hub: 

  1. Close QuickBooks and download the most recent version of QuickBooks Tool Hub, version 1.6.0.8.
  2. You should save the file somewhere you can easily find it, such as your Downloads folder or Windows desktop. 
  3. After that, open QuickBooksToolHub.exe and follow the on-screen instructions and agree to the terms and conditions. 
  4. When installation finishes, double-click the QuickBooks Tool Hub icon on your Windows desktop. If you cannot find the icon, search Windows for QuickBooks Tool Hub and select the program.

Then run File Doctor:

  1. From the Tool Hub, go to Company File Issues. 
  2. Click on Run QuickBooks File Doctor, and after it opens, select your company file from the drop-down menu. If you don’t see it, select Browse and search.
  3. Select Check your file and network, and then press Continue. 
  4. Lastly, you need to enter your QuickBooks admin password and select Next.

The scan can take up to five minutes, depending on the size of your company file.

If QuickBooks File Doctor does not open, freezes, or fails to resolve the company-file problem, see our guide on QuickBooks File Doctor Not Working.

Solution 4: Configure Firewall and Internet Security Settings

A firewall can block QuickBooks from communicating with other computers or accessing network resources. If File Doctor does not resolve the problem, you can configure the firewall manually.

Add a Firewall Port Exception for QuickBooks

If you have multiple versions of QuickBooks Desktop installed on the same computer, perform these steps for each version.

  1. Open the Windows Start menu.
  2. Enter Windows Firewall in the search box and open Windows Firewall.
  3. Select Advanced Settings.
  4. Right-click Inbound Rules and select New Rule.
  5. Select Port and then select Next.
  6. Make sure TCP is selected.
  7. Enter the ports required for your QuickBooks Desktop version:
    • QuickBooks Desktop 2020 and later: 8019, XXXXX
    • QuickBooks Desktop 2019: 8019, XXXXX
    • QuickBooks Desktop 2018: 8019, 56728, 55378-55382
    • QuickBooks Desktop 2017: 8019, 56727, 55373-55377
  8. Select Next.
  9. Select Allow the Connection, then Next.
  10. If prompted, make sure all profiles are marked and select Next.
  11. Create the rule and give it a name such as QBPorts(year).
  12. Select Finish.

Solution 5: Create Windows Firewall Exceptions for QuickBooks Programs

If the problem continues, create firewall exceptions for the QuickBooks executable files.

  1. Open the Windows Start menu. 
  2. Search for Windows Firewall and open it.
  3. Select Advanced Settings. 
  4. Right-click Inbound Rules and select New Rule.
    Create new Inbound and Outbound rules for QuickBooks
  5. Select Program and then Next. 
  6. Select This Program Path and then Browse. 
  7. Find and select the required QuickBooks executable file and select Next. 
  8. Select Allow the Connection and then Next. 
  9. If prompted, make sure all profiles are marked and select Next. 
  10. Create the rule and give it a name such as QBFirewallException(name.exe).

Repeat these steps for outbound rules by selecting Outbound Rules in step 4.

Solution 6: Use a UNC Path instead of a Mapped Drive

If QuickBooks cannot access the company file through a mapped drive, try opening it using a UNC path instead.

  1. Right-click the QuickBooks icon on your desktop.
  2. Press and hold the Ctrl key, then select Run as Administrator.
  3. Continue holding Ctrl until the No Company Open window appears.

Note: Holding Ctrl prevents QuickBooks Desktop from automatically opening a company file.

  1. Go to File > Open or Restore Company > Open a company file, then select Next.
    File - Open or Restore Company in QuickBooks
  2. Select Network from the left panel.
  3. Navigate to the location where your company file is saved.  
  4. Select the company file and select Open.

Solution 7: Recreate the Damaged Folder

If the company file still cannot be opened after changing the file path, the folder containing it may be damaged. Creating a new folder and moving a copy of the company file there can help resolve the issue.

  1. First, create a new folder on your C: drive and open the folder where the company file is saved. 
  2. Then, locate the .qbw file. 
  3. Right-click the .qbw file and select Copy. 
  4. Open the new folder, then Paste the file over there. 
  5. You should set the required Windows access permissions for sharing the company file.  
  6. Lastly, open QuickBooks Desktop and open the file from the new location. 

Solution 8: Remove Spaces after the Company Name and before the Company File Extension

If moving the company file to a new folder does not resolve the issue, check the company file name for unnecessary spaces that may prevent QuickBooks from opening it.

  1. Start by logging out of QuickBooks Desktop on all computers
  2. Proceed to open the folder where the company file is stored.
  3. Choose Rename by right-clicking on the company file.
  4. Select the name of the file, then check and remove any spaces between the file extension and the name of the company.
  5. Now, try to open or create a company file.

Solution 9: Turn off hosting with each computer where QuickBooks is installed

For Single-User Access:

  1. Go to File > Utilities > Stop Hosting Multi-User Access.
    Stop Hosting Multi-User Access
  2. Select Yes when the confirmation message appears.  
  3. Select Yes when QuickBooks asks you to close the company file.  

For Multi-User Access: 

  1. On each client computer showing the error, open the No Company Open window.  
  2. Select File > Utilities.  
  3. Check whether Stop Hosting Multi-User Access appears.  
  4. If it does, select it and follow the prompts to turn off hosting.  
  5. Try opening the company file again. 

Solution 10: Switch to Hosting Local and Remote Files Mode

This solution is for multi-user access specifically.

  1. Open QuickBooks and press the F2 key to open the Product Information window. 
  2. Locate Local Server Information at the bottom to verify if the hosting is set to local files only. 
  3. Then, select the File menu and Switch to Multi-user Mode.
    Switch to Multi-user Mode
  4. After you open the company file from a network computer, press F2 again.  
  5. This time, you should verify that hosting is set to local files only.  
  6. Make sure the hosting computer turned on so other users can access the company file 

Solution 11: Run the QuickBooks Database Server Manager

The QuickBooks Database Server Manager (QBDBSM) hosts your QuickBooks company files.

  1. Make sure you have the Tool Hub installed first. In the tool hub, select Network Issues in the tool hub. 
  2. Select QuickBooks Database Server Manager, and select Start Scan if you see your company file(s).  If you don’t, browse to the location of your company file and then select Start Scan.
  3. Open QuickBooks again and try to sign in to your company file.

Solution 12: Open a Sample Company File

If QuickBooks still cannot open your company file, try opening a sample company file to determine whether the issue is related to your company file or the QuickBooks program.

  1. Open QuickBooks Desktop.  
  2. From the No Company Open window, select Open a Sample File and choose a sample company file.
    No Company Open in QuickBooks
  3. If it opens successfully, continue with the next applicable solution.  
  4. If the sample file also produces an error, repair your QuickBooks installation.

Solution 13: Copy the Company File to the Desktop

If the sample company file opens successfully, the location of your original company file may be causing the problem. Copying the file to your Desktop can help determine whether the storage location is responsible.

  1. Open the folder containing your company file and locate the .QBW file.  
  2. Right-click it and select Copy. Then, paste the file on your Desktop.  
  3. Hold Ctrl while opening QuickBooks Desktop until the No Company Open window appears.  
  4. Select Open or restore an existing company, browse to the copied file on your Desktop, and open it.  

Solution 14: Close All QuickBooks Processes

If the company file still will not open from the Desktop, QuickBooks processes running in the background may be interfering with access. End these processes from Task Manager before trying again.

  1. Sign in to the server computer as an administrator and press Ctrl + Shift + Esc to open Task Manager.
    QuickBooks in Task Manager
  2. Select Users to view processes for all users.  
  3. Find the QuickBooks processes, including QBW32.EXE, qbupdate.exe, and QBDBMgr.exe.
    QBW32.EXE, qbupdate.exe, and QBDBMgr.exe in Task Manager
  4. Select each process and choose End Task.  
  5. Open the company file in Multi-User Mode. 

Solution 15: Run the Quick Fix my Program tool on the client computer

If closing the background processes does not resolve the problem, use Quick Fix my Program to repair common program-related issues on the affected workstation.

  1. Download and install the QuickBooks Tools Hub on the client computer. You will use this tool to run Quick Fix my Program. 
  2. In the QuickBooks Tools Hub, select Program Problems. 
  3. Select Quick Fix my Program. 
  4. Start QuickBooks Desktop and open your data file.

Solution 16: Check your backup filename

If you encounter the issue while restoring a backup, check the backup file and its folder for spaces, symbols, or special characters that could interfere with the restoration process.

Make sure there aren’t any symbols, special characters, or spaces in your backup company filename or the folder holding it. 

  1. Open the Windows Start menu.
  2. Type “File Explorer” into the search and open File Explorer.
  3. Find and open the folder with your backup company file.
  4. Right-click the file with .QBB at the end of the file name and select Rename. This is your backup company file (also known as a QBB file).
  5. Remove any special characters, symbols, or spaces from the filename.
  6. Right-click the folder holding the QBB file and select Rename. Remove any special characters, symbols, or spaces.
  7. Follow the steps to restore your company file.

Solution 17: Check Hosting on Workstations

When you use QuickBooks in a multi-user environment, incorrect hosting settings on a workstation can prevent users from accessing the company file. Check the hosting status on each workstation.

  1. Make sure only one computer or server hosts the company files.
  2. Open QuickBooks Desktop on each workstation.
  3. Press F2 to open the Product Information window.
  4. Check Local Server Information.
  5. Make sure hosting is turned off on the workstations.

Solution 18: Check Folder Permissions

If hosting settings are configured correctly but QuickBooks still cannot access the company file, insufficient Windows permissions on the file’s folder may be preventing access.

  1. Open the folder where the company file is stored.
  2. Check whether the folder has the required Windows permissions.
  3. Update the permissions if necessary.
  4. Try opening the company file again.

Solution 19: Run QuickBooks as Administrator

Running QuickBooks with administrator privileges can help when Windows permissions prevent the company file from opening.

  1. Close QuickBooks.
  2. Right-click the QuickBooks icon.
  3. Select Run As Administrator.
    QuickBooks Run as administrator
  4. Try to open the company file again.

Solution 20: Ensure the Company File Is Not Set as Read-Only

A QuickBooks company file should not be marked as Read Only when you are trying to open it.

  1. Locate the company file in Windows Explorer.
  2. Right-click the company (.QBW) file.
  3. On the General tab, make sure Read Only is not checked.
  4. If it is checked, clear the checkbox and select OK.
  5. Try opening the file again.
