QuickBooks H505 error

QuickBooks is a powerful accounting tool that many businesses rely on for managing financial records. While QuickBooks works flawlessly in most cases, users may occasionally encounter the QuickBooks H505 error, especially when using the software in a multi-user environment. This error can be a major inconvenience, particularly when you need to access your company file on a different computer or server.

The QuickBooks H505 error typically occurs when QuickBooks cannot connect to the company file hosted on a different system, which can happen in multi-user setups. This error is usually caused by network or configuration issues, firewall problems, or QuickBooks settings that are not correctly configured for multi-user mode. If left unresolved, it can cause significant disruption to your workflow.

In this comprehensive guide, we will explore the QuickBooks H505 error in detail, explaining the common causes and providing step-by-step solutions for repairing network and multi-user configurations. We’ll also address frequently asked questions (FAQs) and provide information on how to contact QuickBooks support for further assistance if needed.









What is the QuickBooks H505 Error?

The QuickBooks H505 error typically arises when QuickBooks cannot access the company file stored on a different computer or server in a multi-user network setup. When QuickBooks operates in multi-user mode, the company file is hosted on a server, and multiple users can access it at the same time. However, when there are issues with network connectivity, hosting configuration, or system permissions, the H505 error can occur, preventing QuickBooks from accessing the file.

You may encounter the QuickBooks H505 error if the following occurs:

  • QuickBooks is unable to communicate with the server where the company file is hosted.

  • QuickBooks cannot open the company file because of network connectivity issues.

  • Firewall or antivirus software blocks QuickBooks from accessing the server.

  • QuickBooks is not configured correctly for multi-user mode.

The error message associated with the QuickBooks H505 error generally reads as:

“This company file is on another computer, and QuickBooks needs your permission to access it.”

Symptoms of QuickBooks H505 Error

When you experience the QuickBooks H505 error, you may encounter one or more of the following symptoms:

  • QuickBooks will not open or connect to the company file.

  • The company file cannot be found or accessed when attempting to open it in multi-user mode.

  • QuickBooks freezes or crashes when attempting to load the company file.

  • QuickBooks displays the error message: "This company file is on another computer, and QuickBooks needs your permission to access it."

If you experience any of these issues, it is highly likely that the H505 error is causing the disruption.


Common Causes of QuickBooks H505 Error

Before diving into the solutions, it is essential to understand the most common causes of the QuickBooks H505 error. By identifying the root cause, you can implement the most effective solution.

1. Incorrect Hosting Configuration

  • QuickBooks has two modes: single-user and multi-user. If the hosting configuration is not set up correctly, QuickBooks cannot connect to the company file on the server. This misconfiguration is often the leading cause of the H505 error.

2. Network Connectivity Issues

  • QuickBooks relies on a stable network connection to access the company file on the server. Any disruptions in the network connection or poor network configuration can trigger the H505 error, preventing QuickBooks from connecting to the server.

3. Firewall or Antivirus Blocking QuickBooks

  • Firewalls and antivirus programs can block QuickBooks from accessing the company file on the server. This can happen when the firewall is not configured to allow QuickBooks through or if the antivirus program mistakenly detects QuickBooks as a threat.

4. Corrupt or Incomplete QuickBooks Installation

  • If QuickBooks is not installed correctly, certain files or configurations may be missing or corrupted, which can prevent QuickBooks from accessing the company file. This can lead to the H505 error.

5. Issues with QuickBooks Database Server Manager

  • QuickBooks Database Server Manager (QBDBSM) is responsible for managing access to the company file in a multi-user setup. If the Database Server Manager is not installed correctly or is malfunctioning, the H505 error can occur.








How to Repair the QuickBooks H505 Error: Step-by-Step Solutions

Now that we’ve identified the common causes of the QuickBooks H505 error, let’s go over the troubleshooting steps to resolve the issue.

Step 1: Verify Hosting Configuration

Incorrect hosting configuration is one of the most common causes of the H505 error. Ensure that hosting is configured correctly on both the server and client computers.


On the Host Computer (Server Computer):

  1. Open QuickBooks on the computer that holds the company file (the server).

  2. Go to File > Utilities.

  3. Select Host Multi-User Mode. If this option is not selected, click it to enable hosting.


On Client Computers (Computers Accessing the Company File):

  1. Open QuickBooks on each client computer.

  2. Go to File > Utilities.

  3. Ensure that Multi-User Mode is selected. If it is not, select it.

After completing this, restart QuickBooks and check if the error is resolved.


Step 2: Check Firewall and Antivirus Settings

Firewalls and antivirus software often block QuickBooks from communicating over the network, causing the H505 error. Here’s how to fix it:

  1. Temporarily Disable Antivirus or Firewall:

    • Disable the firewall or antivirus on both the server and client computers temporarily to see if the H505 error goes away. If it does, you’ll need to add QuickBooks to the exception list.


  1. Add QuickBooks to the Firewall and Antivirus Exception List:

    • Open your firewall or antivirus software and add the following QuickBooks applications to the exception list:

      • qbupdate.exe

      • qbdbmgrn.exe

      • qbw32.exe

    • Open the necessary ports for QuickBooks, such as 8019, 56728, and 55383, to ensure proper communication.


  1. Re-enable Antivirus/Firewall:

    • After adding QuickBooks to the exception list, re-enable your firewall and antivirus software. Check if the H505 error is resolved.


Step 3: Repair or Reinstall QuickBooks

If QuickBooks is not properly installed or the installation is corrupted, it can result in the H505 error. Follow these steps to repair or reinstall QuickBooks:

  1. Repair QuickBooks:

    • Open Control Panel > Programs and Features.

    • Select QuickBooks from the list of installed programs and click Uninstall/Change.

    • Choose Repair and follow the on-screen instructions to repair QuickBooks.


  1. Reinstall QuickBooks:

    • If repairing QuickBooks does not resolve the issue, uninstall QuickBooks and reinstall it.

    • Be sure to back up your company files before uninstalling.

    • Reinstall QuickBooks and check if the H505 error is resolved.


Step 4: Install or Repair QuickBooks Database Server Manager

QuickBooks Database Server Manager (QBDBSM) is essential for managing multi-user access to the company file. If this service is not installed or is misconfigured, the H505 error can occur.

  1. Download and Install QuickBooks Database Server Manager:

    • Download the QuickBooks Tools Hub and install it on both the server and client computers.

    • Use the tools in the hub to repair or reinstall QuickBooks Database Server Manager.

  2. Restart QuickBooks:

    • After installing or repairing QBDBSM, restart QuickBooks to see if the error is resolved.


Step 5: Verify Network and File Sharing Settings

Network and file sharing issues can prevent QuickBooks from accessing the company file. Verify that your network settings are correct:

  1. Check Network Connectivity:

    • Ensure that all systems (server and clients) are connected to the same local network.

  2. Enable File Sharing:

    • Make sure the folder containing the company file is shared on the network.

    • Right-click the company file folder > Properties > Sharing tab > Share this folder.

  3. Restart Network Devices:

    • Restart your router, switches, or any other network devices to resolve any temporary connectivity issues.
