QuickBooks Error H202: Causes, Solutions, and Prevention

by

QuickBooks is widely recognized for its efficient accounting and bookkeeping capabilities, but like any software, it is prone to errors. One common issue QuickBooks users encounter is Error H202, which typically arises when switching to multi-user mode. This error can disrupt workflow, especially for businesses relying on QuickBooks for real-time collaboration between multiple users. In this article, we will dive deep into the causes, symptoms, solutions, and prevention methods for QuickBooks Error H202.

What is QuickBooks Error H202?

QuickBooks Error H202 occurs when QuickBooks cannot communicate with the company file located on another server or computer. It is a multi-user mode error, meaning it typically arises when a user tries to access a company file stored on a server (not on their local machine) in a multi-user setup. The error indicates that the multi-user hosting setup is being blocked or interrupted, leading to communication issues between the QuickBooks desktop and the server.

When this error occurs, you might see the following error message:

“Error H202: This company file is on another computer, and QuickBooks needs some help connecting.”

Common Causes of QuickBooks Error H202

Understanding the causes of Error H202 can help address the problem more efficiently. Here are the common reasons behind this error:

  1. Incorrect Hosting Configuration: If the settings for hosting the QuickBooks company file are not configured properly on the server, Error H202 may occur.
  2. Firewall Blocking Communication: The firewall on your system may block the incoming and outgoing communication between QuickBooks and the server that hosts the company file.
  3. Damaged or Corrupt Network Data (ND) File: The ND file helps QuickBooks access the company file over a network. If this file is damaged or corrupt, it can prevent communication between the desktop and the server.
  4. DNS Server Issues: Incorrect DNS settings or issues with the domain name system (DNS) can block the QuickBooks Desktop from locating the IP address of the server hosting the company file.
  5. QuickBooks Database Server Manager Not Running: The Database Server Manager allows multi-user access to the company file. If it isn’t running on the server, users might face Error H202.
  6. Server Not Reachable: If the QuickBooks server is turned off, down, or unreachable due to network issues, the error might occur.

Symptoms of QuickBooks Error H202

If your system is encountering Error H202, you may notice the following symptoms:

  • QuickBooks runs slowly or becomes unresponsive when trying to access the company file.
  • You are unable to switch QuickBooks to multi-user mode.
  • The following error message pops up: Error Code H202.
  • A system crash or freeze may occur when accessing the QuickBooks multi-user mode.
  • The user may not be able to open the company file hosted on the server.

Solutions to Fix QuickBooks Error H202

There are several methods to fix Error H202, ranging from simple troubleshooting steps to more advanced configurations. Here’s a step-by-step guide to resolving the error:

Method 1: Check QuickBooks Hosting Settings

To resolve this error, make sure that hosting is turned off on workstations but enabled on the server:

  1. Open QuickBooks on each workstation.
  2. Go to File > Utilities.
  3. If you see the option Stop Hosting Multi-User Access, select it. If you see Host Multi-User Access, do not select it, as it means hosting is already off on that workstation.

On the server:

  • Ensure that Host Multi-User Access is enabled on the server that hosts the QuickBooks company file.

Method 2: Use QuickBooks File Doctor

QuickBooks File Doctor is an in-built tool designed to diagnose and fix common QuickBooks issues, including network errors like H202.

  1. Download and install the QuickBooks Tool Hub if you don’t already have it.
  2. Open the Tool Hub, and go to the Company File Issues section.
  3. Select Run QuickBooks File Doctor.
  4. Browse to the company file location and select it.
  5. Let the File Doctor scan and fix the issues.

Method 3: Configure Firewall Settings

The firewall may be blocking communication between the workstations and the server. Here’s how to configure firewall settings to allow QuickBooks access:

  1. Open the Control Panel and go to Windows Firewall.
  2. Click on Advanced Settings.
  3. In the Inbound Rules, create a new rule for the following executable files:
    • QBDBMgrN.exe
    • QBW32.exe
    • QBUpdate.exe
    • IntuitSyncManager.exe
  4. Do the same under Outbound Rules.
  5. Once done, restart the system and see if the issue is resolved.

Method 4: Use QuickBooks Database Server Manager

Ensure that the QuickBooks Database Server Manager is running on the server:

  1. Open the QuickBooks Tool Hub.
  2. Select Network Issues, and then choose QuickBooks Database Server Manager.
  3. Scan the folder where the company file is located.
  4. After scanning, check if the issue is resolved.

Method 5: Add Server to Host File

Another solution to fix network connectivity issues is to add the server’s IP address and hostname to the Windows Host File:

  1. Navigate to **C:\Windows\System32\Drivers\Etc**.
  2. Open the Host file with Notepad.
  3. Enter the server’s IP address and the computer name at the bottom of the file.
  4. Save the changes and restart the computer.

  • Use a Reliable Network: Make sure that the server is always accessible and that there are no network interruptions.
