QuickBooks Error H202 and H505: Common Causes & Proven Solutions

QuickBooks is a powerful accounting software used by millions of small and medium-sized businesses. However, like any complex software, it can encounter errors, especially when it comes to network connectivity or multi-user mode. Two common errors that many QuickBooks users face are H202 and H505. These errors can be frustrating, especially when they interrupt your workflow. In this post, we’ll dive into the common causes behind these errors and provide proven solutions to help you resolve them quickly.

What are QuickBooks Errors H202 and H505?

Before we dive into solutions, let’s briefly understand what these errors mean:

• Error H202: This error typically occurs when QuickBooks is unable to connect to the company file on the server. It’s common when QuickBooks is running in multi-user mode and the system is unable to access the required company file because of network issues.

• Error H505: This error occurs when QuickBooks is unable to connect to the server or the computer hosting the company file. It generally points to issues with the server or firewall settings, preventing the system from accessing the company file over the network.

Common Causes of QuickBooks Errors H202 and H505

Understanding the root causes can help in efficiently addressing the problem. Here are the most common reasons for these errors:

1. Incorrect Hosting Configuration: If the hosting setup for multi-user mode is incorrect or inconsistent between computers, QuickBooks can fail to connect to the company file, triggering error H202 or H505.
2. Firewall or Antivirus Blocking Connection: Firewalls or antivirus software can block communication between the QuickBooks client and the server, especially if the ports required for QuickBooks are not properly configured.
3. Corrupted Company File: A damaged or corrupted company file can lead to errors when trying to access it from a different machine.
4. Damaged or Misconfigured Network: QuickBooks needs a stable network to operate in multi-user mode. If the network configuration is not set up properly, or if there are issues with the server hosting the company file, errors H202 and H505 are likely to occur.
5. QuickBooks Database Server Manager Issues: QuickBooks relies on the Database Server Manager (DSM) to manage access to the company file. If this service is not running or is corrupted, you might face these errors.
6. Outdated QuickBooks or Windows Versions: Running an outdated version of QuickBooks or Windows can sometimes cause compatibility issues, leading to network-related errors like H202 and H505.
