Why Does Error Code 6000 In QuickBooks Occur?

The following are the main reasons why the Error Code 6000 in QuickBooks appears.

• Problem with the file location or incorrect file path.
• The users often fail to access the company file due to network-related issues.
• Blockage of the Windows Firewall might also prevent you from using the data file.
• Running an old QuickBooks Desktop or Windows operating system.
• It may occur due to damaged or corrupted company files.
• Insufficient user permissions or access restrictions.

How to Fix Error 6000 When Opening a Company File in QuickBooks?

After understanding the root causes, let’s explore the solutions to address Error 6000 when opening a company file in QuickBooks.

Solution 1: Update QuickBooks Desktop to the latest release

The first solution is to ensure that you are using the latest version of QuickBooks Desktop. The older QuickBooks version might prevent users from accessing the data file, resulting in QuickBooks Desktop Error 6000. So, to fix the issue, you must update QuickBooks Desktop to the latest release.

Solution 2: Use the QuickBooks File Doctor Tool

Sometimes, the users may experience QuickBooks Company File Error 6000 due to damage or a corrupt company file. So, to resolve the issue, you must run the QuickBooks File Doctor tool. Once you run this utility, it will scan for the damage within the file and then run a repair to fix it.

Solution 3: Change the Name of.ND and TLG Files

Both the.ND and the.TLG is the essential QuickBooks file that lets users access the data file in a network or multi-user environment. In case these files get damaged, you might receive Error 6000 in QuickBooks Desktop. So, giving a new name to these files will save your data from getting damaged. Later on, QuickBooks generates these files again every time you scan the QBDBMgrN, and then you can access the files.
Go through the steps below for changing the name if the.TLG and .ND files.

• Initially, access the company file folder that is holding your company file.
• After this, look for the file names having similar names but with different extensions, say .ND and.TLG.
  • company_file.qbw.nd
  • company_file.qbw.tlg
• Now, right-click on the .ND and then the .TLG files. Then, click on the Rename option from the list of options.
• Thereon, insert .OLD at the end of these file names.
• When you have changed both the file names, launch the QuickBooks application. Then, access your data file and see if the error still continues.

Solution 4: Try Accessing the Sample Company File

If you still fail while accessing your company file, then try opening a sample file. Doing so will help you spot whether the issue lies with the QuickBooks application or with the data file itself. In case your sample file fails to open and prompts you with an error, it’s an indication that your QuickBooks installation is damaged. In that scenario, you need to fix the issues with the installation of QuickBooks.

• Access the No Company Open window and choose the Open a Sample file option.

• After this, pick any sample company file from the available options.
• Now, if you are able to launch your data file, then try the next solution. Otherwise, you are getting the same error message, then access the QuickBooks Install Diagnostic Tool.

Solution 5: Copy Your Company File to Your Desktop

After copying the file to the desktop, open it and test whether the issue lies with the location of your data file.

• If your data file opens from the desktop, it states that there is damage within the location of the file.
• There might be the possibility that your data file is saved in too many folders, which exceeds the system path limitation.
• If you are still unable to launch the file after changing the location, it means that your file is damaged.
• Go to the QuickBooks folder that holds your company file.
• Now, start looking for the file having .QBW extension, right-click on it and hit the Copy option.
• Move to the desktop, right-click anywhere on the desktop, and choose the Paste option.
• Keep holding the Ctrl key and then launch the QuickBooks application. With this, it will take you to the No Company Open window.
• Choose the Open or restore an existing company option. Move to your desktop and look for the data file.
• Access the company file and see if the Error 6000 in QuickBooks still appears.

In case you are still getting Error 6000 When Opening a Company File in QuickBooks, apply the solution depending on how you launch your file.

Instance 1: If you open your company file locally

It means that you launch your company file on the same computer on which you installed the QuickBooks application.

Solution 1: Try to Restore the Backup Of the Company File

If you get QuickBooks Company File Error 6000, try restoring the company file backup to determine whether the issue is with your current QuickBooks file.

• Firstly, see whether your computer isn’t hosting:
  • Launch your QuickBooks data file and click the File menu.
  • Tap on the Utilities option and then move further.
  • Now, verify if the Stop Hosting Multi-User Access option is listed:

• Hit the Stop Hosting Multi-User Access option.
• Choose the Yes option from the Stop hosting multi-user access option.
• Opt for the Yes menu in the company file, but in a closed window.
• Afterwards, check that the path to your company file doesn’t exceed 210 characters.
  • Return to the location of your data file.
  • Now, copy the path from the address bar.
  • Thereon, paste the path into Notepad and then count the characters along with the spaces.
• Next, you must try to restore your QuickBooks data file.

Solution 2: Access the Auto Data Recovery For Restoring the Backup

If you get the Company File Error Code 6000 in QuickBooks, then you can recover QuickBooks data files. Running the QuickBooks ADR tool will help you regain access to the lost data. Thus, it will help you regain access to your data files so that you can resume your work without any hassle.

Instance 2: When you open the file over the network

Herein, it is advised that you must access one computer or the server for hosting the data files.

• Initially, hit the F2 key to launch the Product Information screen.
• After this, look for the Local Server Information. Then, start verifying that hosting is disabled.

Solution 2: Access the QuickBooks Database Server Manager

The QuickBooks Database Server Manager is used for hosting the QuickBooks data files. So, to fix the issue, you must restart the QB Database Server manager and then run a scan on the company files after changing the name.ND and .TLG files.

• Open the QuickBooks Tool Hub and then hit the Network Issues tab.
• After this, choose the QuickBooks Database Server Manager tab. Then, start installing QuickBooks on your server if you haven’t installed it earlier.
• When you are in the QuickBooks Database Server Manager screen, try to log in to your company files. Then, check whether the issue is still interrupting you.

Solution 3: Shut Down all QuickBooks Processes

• Firstly, login to your server computer as an Administrator.
• After this, launch the Task Manager by pressing the Ctrl + Esc + Shift keys.
• Now, show processes for all users and click on the Users tab.
• You must choose each QuickBooks process: QBW32.EXE, qbupdate.exe, and QBDBMgr.exe. Then, tap on the End Task option.
• Finally, launch your company file in multi-user mode.

Solution 4: Verify the Folder Permissions Manually

• Now, right-click on the QuickBooks company file folder and tap on Properties.

• Thereon, generate a new rule and assign a new name “QBPorts(year)”.
