When QuickBooks Desktop displays the message QBCFMonitorService Not Running on This Computer, it usually indicates a problem with the service responsible for supporting company file monitoring in a multi-user environment. This can prevent employees from accessing shared company files, interrupt network connections, or cause QuickBooks Database Server Manager to fail during a folder scan.
The issue may occur because the service has stopped, QuickBooks components are damaged, or Windows security settings are interfering with communication. Follow the troubleshooting methods below to identify and resolve the problem.
What Is QBCFMonitorService in QuickBooks?
QBCFMonitorService is a Windows background service associated with QuickBooks Desktop. It works with the QuickBooks hosting environment to support access to company files stored on a network.
It is particularly relevant when multiple users access the same company file through a server or host computer. If the service fails to start or communicate correctly, QuickBooks may display a warning that it is not running.
Common Causes of QBCFMonitorService Not Running
Several issues can prevent the service from working correctly:
- Service is stopped: QBCFMonitorService may have stopped unexpectedly or failed to start with Windows.
- Incorrect service configuration: Windows service startup settings may prevent it from launching automatically.
- Damaged QuickBooks components: Missing or corrupted installation files can interfere with the service.
- Firewall restrictions: Windows Defender Firewall or third-party security software may block QuickBooks network communication.
- Outdated Database Server Manager: An incompatible or outdated server component may cause connection problems.
- Incorrect hosting configuration: Hosting may be enabled on a workstation instead of the computer storing the company file.
How to Fix QBCFMonitorService Not Running on This Computer
Try the following solutions in order. Before making changes, ask other users to close their company files if you are working on a shared server.
1. Start or Restart QBCFMonitorService
First, check whether the service is running on the computer hosting the company file.
- Press Windows + R to open the Run dialog box.
- Type
services.mscand press Enter. - Find QBCFMonitorService in the service list.
- Right-click it and select Start if it is stopped.
- If it is already running, consider selecting Restart during a maintenance period.
- Open the service properties and review its Startup type.
- Apply the appropriate startup setting for your installation.
After restarting the service, reopen QuickBooks and check whether the message disappears.
2. Check QuickBooks Database Server Manager
QuickBooks Database Server Manager helps configure folders containing company files for network access.
- Open the Windows Start menu.
- Search for QuickBooks Database Server Manager.
- Launch the program on the host computer.
- Select the Scan Folders tab.
- Confirm that the folder containing your company file is listed.
- If it is missing, select Browse and add the correct folder.
- Click Start Scan and wait for the process to finish.
If the scan fails, review its diagnostic message instead of repeatedly running it. You can also explore this guide to QuickBooks Database Server Manager for additional setup information.
3. Review Windows Firewall Settings
Firewall restrictions can interfere with communication between QuickBooks workstations and the host computer.
- Open Windows Security from the Start menu.
- Select Firewall & network protection.
- Open the advanced firewall settings.
- Review the inbound and outbound rules for QuickBooks.
- Confirm that the required QuickBooks programs and network ports are permitted.
- Check whether third-party antivirus software has separate firewall settings.
Intuit lists QBCFMonitorService.exe among the QuickBooks components that may require firewall exceptions. Confirm the installed file location and follow the firewall requirements for your QuickBooks version before creating rules.
4. Update QuickBooks Desktop
An outdated QuickBooks installation or Database Server Manager can contribute to service problems.
- Open QuickBooks Desktop.
- Select Help and choose Update QuickBooks Desktop.
- Open the Update Now tab.
- Select the available updates.
- Click Get Updates.
- Restart QuickBooks after the updates finish.
If your server uses Database Server Manager separately, make sure its version is compatible with the QuickBooks installation.
5. Repair QuickBooks Installation
Damaged program components may prevent the monitoring service from starting.
- Close QuickBooks and other related programs.
- Open the Windows Control Panel.
- Select Programs and Features or Uninstall a Program.
- Locate QuickBooks Desktop.
- Select Uninstall/Change.
- Choose the Repair option if it is available.
- Follow the on-screen instructions and restart the computer.
Create a backup of your company file before performing installation repairs.
6. Reinstall QuickBooks Database Server Manager
If the service continues to fail on the host computer, Database Server Manager may need to be reinstalled.
Before proceeding, confirm that you have a separate backup of the company file and know which QuickBooks version is installed.
- Press Windows + R.
- Enter
appwiz.cpland press Enter. - Find QuickBooks Database Server Manager in the installed programs list.
- Select it and choose Uninstall/Change.
- Follow the removal instructions.
