Hey there, @Ben23_1. Thanks for joining the thread and sharing the troubleshooting steps that you've done.
I'd like to share some additional steps that may help address the issue.
QBCFMonitorService may stop working on Windows due to several reasons.
- Windows Defender and third-party firewall applications restrict QuickBooks connection with the company file that you have stored on the server
- The server on which you have installed QuickBooks isn't up correctly to host company files in a multi-user environment
- A virus or malware attack has corrupted your QBCFMonitorService.exe.file
- There might be some issue with the Windows registry
To fix the problem, let's try restarting QBCFMonitorService.exe. Here are the steps:
- Press Ctrl + Alt + Del keys to open the task manager and then go to the Processes menu.
- Right-click on the QBCFMonitorService process and choose the option End Task.
- Click Yes to confirm.
- Open the QuickBooks application again.
Before performing the steps, make sure to back up your QuickBooks Desktop company file to safeguard your data while in the process.
If you're still getting the same results, let's scan your system using antivirus software. Then, re-download the QBCFMonitorService.exe file and replace the one stored in the QuickBooks folder.
If the issue persists, I'd suggest contacting our QuickBooks Desktop Support Team. They have the expertise and tools to diagnose the cause of the problem and provide a solution.
Moreover, here's the list of features and tasks that can be performed in two different hosting modes: Features and tasks available in single or multi-user mode.
Let me know if you have follow-up questions. I'm always here to help. Take care.
