Why Is QBCFMonitorService Not Running on Your Computer? Explained

 QuickBooks is an indispensable tool for businesses of all sizes, but it isn't without its hiccups. One common issue users face—especially on newer systems like Windows 11—is the “QBCFMonitorService Not Running on Your Computer” error. This error can be a major roadblock, especially when it's tied to the QuickBooks Error 3371 Status Code 11118. In this article, we’ll explore what QBCFMonitorService is, why it stops running, how it relates to error 3371, and most importantly, how to fix it.

What is QBCFMonitorService?

QBCFMonitorService stands for QuickBooks Company File Monitor Service. It is a background process installed with QuickBooks to facilitate seamless multi-user access, company file monitoring, and network communications. When this service stops working, it may cause problems such as QuickBooks not opening, crashing, or multi-user mode not functioning properly.

The Error: “QBCFMonitorService Not Running on Your Computer Windows 11”

If you’re seeing this error on Windows 11, it typically means the QBCFMonitorService is disabled, corrupted, or being blocked by third-party software like antivirus or firewall settings. When this service fails, it affects the network-related functionalities of QuickBooks, especially in multi-user environments.

Related Problem: QuickBooks Error 3371 Status Code 11118

The QuickBooks Error 3371 Status Code 11118 often appears alongside the QBCFMonitorService issue. This error occurs when QuickBooks cannot load the license data. Reasons for this may include:

  • Corrupted or missing EntitlementDataStore.ecml file

  • Damaged MSXML or .NET Framework components

  • Antivirus software blocking key services

  • Improper system shutdown or OS update

These issues are interlinked—when system services like QBCFMonitorService fail, it can disrupt license validation and trigger error 3371.

What Causes QBCFMonitorService to Stop Working?

Several issues can prevent QBCFMonitorService from running on your Windows 11 system:

1. Windows 11 Compatibility

While QuickBooks supports Windows 11, older versions may not work well with the OS’s newer security and system configurations.

2. Corrupt QuickBooks Installation

Incomplete or damaged installations can affect key services, including QBCFMonitorService.

3. Disabled Service

The service may be disabled in the Windows Services manager either manually or by third-party software.

4. Antivirus/Firewall Interference

Security software may mistakenly identify QBCFMonitorService as a threat, blocking it or limiting its permissions.

5. Network Configuration Errors

Incorrect host settings or broken network configurations may also prevent this service from starting.

  4. Set Startup Type to Automatic.

If the service fails to start, move to the next steps.

Step 2: Add Antivirus and Firewall Exclusions

  1. Open your antivirus settings.

  2. Add these folders to your exclusions:

    • C:\Program Files\Intuit

    • C:\ProgramData\Intuit

    • QuickBooks executable files like QBW32.exe, QBDBMgrN.exe, and QBCFMonitorService.exe
