What Is QuickBooks Error H202? Causes, Troubleshooting, and Support Guide

QuickBooks is a powerful accounting software used by small to mid-sized businesses for managing finances, payroll, invoices, and more. However, like any software, it can sometimes face technical issues. One such common multi-user issue is QuickBooks Error H202. This error can hinder your team’s ability to access the company file stored on a server from other workstations. Understanding its root causes, symptoms, and solutions is essential to restoring functionality.


In this comprehensive guide, we will explore everything about QuickBooks Error H202, how it differs from other errors like QuickBooks Error Code 15276, and how to fix it with or without expert assistance.


Section 1: Understanding QuickBooks Error H202


QuickBooks Error H202 typically occurs in a multi-user environment when a workstation fails to connect to the company file located on another computer (server). This error indicates a communication barrier between the system trying to access the file and the server hosting the file.


Error Message:“You are trying to work with a company file located on another computer, and this copy of QuickBooks cannot reach the server on that computer.”

This message confirms the system cannot establish a connection to the host system. If not addressed immediately, it can halt your accounting workflow.


Section 2: Causes of QuickBooks Error H202


Several factors can cause QuickBooks Error H202, including:

  1. Incorrect Hosting Configuration

    • Workstations are not set to the correct hosting settings.

  2. Blocked Communication Ports

    • Required QuickBooks ports are blocked by the firewall or antivirus.

  3. QuickBooks Services Not Running

    • QuickBooks services like QBCFMonitorService or QuickBooksDBXX are disabled or not running properly.

  4. DNS Issues

    • Domain Name System settings may be incorrect or not resolving the server name correctly.

  5. Damaged or Corrupt .ND File

    • The .ND (Network Descriptor) file is required to access the company file in a network. If this file is damaged, it may prevent access.

  6. Third-party Firewall or Security Software

    • Security applications may block incoming or outgoing data needed for communication.

Section 3: Symptoms of QuickBooks Error H202



You might be facing Error H202 if you notice any of the following:

  • Inability to switch QuickBooks to multi-user mode.

  • QuickBooks freezes or responds slowly when opening the company file.

  • A system crash when accessing the company file on another computer.

  • Frequent disconnection from the server.

  • Error message with code H202 displays on the screen.


Section 4: Relation to QuickBooks Error Code 15276


Though QuickBooks Error Code 15276 is different from H202, users may encounter both when dealing with update or connectivity issues.


QuickBooks Error Code 15276 is generally related to payroll updates:

“The payroll update did not complete successfully. One of the files cannot be validated.”

In contrast, Error H202 is network-related. However, both errors can sometimes appear together if there’s a deeper system misconfiguration, outdated QuickBooks version, or firewall blocking essential files.


Section 5: How to Fix QuickBooks Error H202

Here is a step-by-step guide to resolving QuickBooks Error H202:


Step 1: Use the QuickBooks Tool Hub

  1. Download the latest version of the QuickBooks Tool Hub from Intuit’s official site.

  2. Install and open the tool.

  3. Navigate to Network Issues tab.

  4. Select QuickBooks Database Server Manager.

  5. Scan the folder where your company file is stored.

  6. After the scan, try opening the file again in multi-user mode.


Step 2: Verify Hosting Settings

On all workstations:

  1. Open QuickBooks > File > Utilities.

  2. If you see “Host Multi-User Access” – don’t select it.

  3. If you see “Stop Hosting Multi-User Access” – click it and disable hosting on workstations.

Only the server computer should host the file.


Step 3: Check QuickBooks Services

  1. Press Windows + R, type services.msc, press Enter.

  2. Find QuickBooksDBXX and QBCFMonitorService.

  3. Ensure both are running and set to Automatic.


Step 4: Configure Windows Firewall

  1. Open Windows Firewall > Advanced Settings.

  2. Add inbound and outbound rules for:

    • TCP: 8019, 56728, 55378–55382

  3. Allow QBDBMgrN.exe and QBCFMonitorService.exe through the firewall.


Step 5: Rename the .ND File

  1. Go to the folder containing your company file.

  2. Look for the file with extension .ND (e.g., CompanyFileName.qbw.nd)

  3. Right-click and rename it to CompanyFileName.qbw.nd.old

  4. Reopen QuickBooks and rescan using the Database Server Manager.


Step 6: Check DNS Settings

  1. Open Command Prompt and type ipconfig /all.

  2. Note the server’s IP address and use it to ping the server from the workstation.

  3. If ping fails, consult your IT professional to correct DNS settings.


Section 6: Preventing QuickBooks Error H202 in Future


To avoid encountering Error H202 again:

  • Always update QuickBooks to the latest version.

  • Maintain a stable and secure network connection.

  • Use a dedicated server to host the company file.

  • Regularly scan for malware and security threats.

  • Avoid third-party software that might block QuickBooks connectivity.

  • Make sure firewalls and antivirus programs allow QuickBooks processes.
