Common Causes of QuickBooks Update Errors

QuickBooks update errors can be caused by a variety of issues, including:

  • Damaged or corrupted company files

  • Incorrect hosting settings

  • Windows Firewall blocking QuickBooks files

  • Damaged DNS settings or network issues

  • Interruption in internet connectivity

  • Outdated QuickBooks versions or missing updates

  • Conflicts with third-party antivirus or software



Understanding QuickBooks Error H202

Before we dive into solutions, it’s essential to understand QuickBooks Error H202 specifically, which is one of the most frequent update-related errors.


What Is QuickBooks Error H202?

QuickBooks Error H202 typically occurs when QuickBooks Desktop is in multi-user mode and can’t connect to the company file located on another computer (the server). This means QuickBooks is unable to communicate with the server due to network or hosting issues.

You may see this error message:

“You are trying to work with a company file that is located on another computer, and this copy of QuickBooks cannot reach the server (H202).”

This is particularly common during or after an update when file paths or permissions might have changed.



Signs You’re Experiencing QuickBooks Error H202

  • QuickBooks freezes or runs slowly in multi-user mode.

  • Error message H202 appears when trying to open a company file.

  • You can't switch to multi-user mode.

  • QuickBooks fails to update or connect to the database server.

Sometimes the issue isn’t with QuickBooks but with your network.

Steps:

  1. On the computer showing the error, go to Start > Command Prompt.

  2. Type ping [servername] and press Enter.

  3. If you get a delayed or failed response, there’s a network issue that needs resolving.
