What Is QuickBooks Error 6189, 816?

QuickBooks Error 6189, 816 is one of the errors in the 6000 series of errors for company file access issues. This error typically happens when:

You attempt to open your company file in a multi-user network.

Another user has the file already open in Single-User Mode. 

There is a mismatch between the QuickBooks Database Server Manager and the company file.

The company file is located on another computer or network drive.

What is annoying about this error is that it doesn’t say a specific file is damaged, even though that would be easier to solve, but a manual or config issue between QuickBooks and where your company file resides. 

Understanding the Causes of QuickBooks Error 6189, 816

To fix an issue correctly, it is easier to understand where it is originating from. Some of the primary reasons for Error 6189, 816 are as follows:

Multi-User Mode Conflict

QuickBooks can run in either Single-User or Multi-User Mode. This is the error that shows up if many users are trying to open the company file, and the software is not configured to cater to it accordingly.

Incorrect Hosting Setup

In case the host machine is not installed with QuickBooks Database Server Manager or in case the file is being opened on a computer that is not configured to act as a host, it will generate this error.

Corrupt or Truncated File Sections

Damaged or missing transaction log files(.TLG files) result in communication problems with the master company file(.QBW).

File Already Opened Elsewhere

If the file is already open by another user, particularly in Single-User Mode, and you attempt to open it, QuickBooks will not allow you to do so, as it will conflict.

Insufficient Permissions

Unpredictable file or directory permissions on the server or workstation can also hinder QuickBooks from opening the file.

Indications That You’re Working with Error 6189, 816

The following are some unmistakable indications:

QuickBooks freezes or crashes when attempting to open the company file.

How to Fix QuickBooks Error 6189,816: 

Step 1: Reboot All Workstations and Servers

Reboot the target systems before making any changes. Often, background system processes can conflict.

Reboot the server computer holding the company file.

Restart any workstations that are opening the file.

Attempt to reopen the company file again.

If still not working, continue to the next step.

Step 2: Use the QuickBooks Tool Hub

Intuit provides a toolset to correct common problems.

Download the QuickBooks Tool Hub from the official Intuit website.

Install and execute it.

Click on the Company File Issues tab.

Click QuickBooks File Doctor and let it scan and fix the file.

This auto program might frequently correct data connectivity and corruption problems.

Step 3: Verify Hosting Settings

Make sure only a single computer, the server, is hosting the company file.

Open QuickBooks on every computer.

Go to File > Utilities.

If you notice "Stop Hosting Multi-User Access," that machine is hosting. Do not leave this on the server computer alone.

On any other computers, you should notice "Host Multi-User Access," indicating that hosting is off.

Multiple hosts create conflict and invoke error codes such as 6189, 816.

Step 4: Verify File Permissions

QuickBooks requires complete control of the folder containing the company file.

Right-click the folder > Properties > Security tab.

Verify Users, Administrators, and QuickBooks Database User have Full Control.

If necessary, modify permissions.

Step 5: Rename the.ND and.TLG Files

The support files sometimes become damaged and lock out access to files.

Go to the directory of your company file.

Find files with the same file name but with different file extensions.ND and.TLG.

CompanyFile.qbw.nd and CompanyFile.qbw.tlg

Right-click both and rename with old on the end.

QuickBooks will restore these files the next time you open the company file.

Step 6: Move the Company File to a Local Drive

As a test, move the company file to your local C: drive.

Copy the file and paste it into a local folder (e.g., C:\\\\\\\\\\\\\\\\\\\\\\\\\\\QBTest).

Open QuickBooks and try to open the file from the new location.

If it opens normally, then the issue is with your network or shared drive.

Step 7: Update QuickBooks

Old applications can cause compatibility problems.

Open QuickBooks.

Go to Help > Update QuickBooks Desktop.

Download and install the updates.

Restart the system after the installation.

Ensure all users have the same version.

How to Prevent QuickBooks Error 6189, 816?

Once fixed, take the following steps so it does not happen again:

Always. Regularly update QuickBooks.

Store the file saved by the host server only in multi-user mode.

Use the QuickBooks Database Server Manager on the host computer.

Do not store the company file in external drives or USBs.

Back up regularly to protect against file corruption.

Educate all users in Single-User vs. Multi-User Mode and practice best practices.

When to Call a Professional?

If you’ve exhausted all the above steps and the error still lingers, it may be time to consult an IT professional or QuickBooks ProAdvisor. They can help with advanced issues like:

Network configuration problems

Server file permission conflicts

Data recovery for corrupted company files
