What Are QuickBooks Errors 6189 and 6190?

QuickBooks Errors 6189 and 6190 typically occur when you try to open a company file in a multi-user setup. They are part of the 6000-series errors and usually signal a mismatch between the company file and transaction log, or issues with server communication. You might see this error if your QuickBooks Database Server Manager is misconfigured or if the QBCFMonitorService is not running on your system.

Why Do These Errors Happen?

These QuickBooks issues are triggered by several underlying problems:

The company file is being accessed by another user
The transaction log file does not match the company file
QBCFMonitorService is stopped or malfunctioning
QuickBooks Database Server Manager is not properly installed or configured
The data file is stored on a server that doesn’t host the company file correctly
Permissions or firewall settings are blocking multi-user access

💥 Must-Know Solutions to Fix These Errors Immediately

✅ Restart QuickBooks Database Server Manager

Go to the system hosting your QuickBooks company file. Open Services, find QuickBooksDBXX, and restart it. This refreshes your server connection and fixes file-sharing issues.

✅ Ensure QBCFMonitorService Is Running

Go to Windows Services, search for QBCFMonitorService, and set its startup type to Automatic. If it's stopped, click Start. This service is crucial for multi-user file communication.

✅ Run QuickBooks Tool Hub

Download the latest version of QuickBooks Tool Hub, then go to the Network Issues tab. Run QuickBooks Database Server Manager from there and scan the folder where your company file is stored.

✅ Rename .ND and .TLG Files

Go to your company file folder. Find the files with extensions .ND and .TLG and rename them by adding “.old” at the end. QuickBooks will automatically recreate them when you relaunch the file.

✅ Use a Local Backup

If the error persists, restore the most recent local backup of your company file and see if the issue still occurs. Data corruption may be the root cause.

✅ Disable Hosting on Workstations

Open QuickBooks on each workstation and go to File > Utilities. If you see “Stop Hosting Multi-User Access,” select it. Hosting should only be enabled on the server.
