Let’s dive in.

What is QuickBooks Error H202?​

QuickBooks Error H202 is a multi-user switching error that occurs when QuickBooks Desktop can’t access the company file located on another computer (the server). This typically happens when:

• You’re trying to access the file from a workstation
• QuickBooks can’t reach the server hosting the file
• Multi-user hosting configuration is broken

You may see this error message:

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

Sounds familiar?


This error is part of the H-series errors, like H101, H303, H505, but H202 is by far the most notorious.

Why Does QuickBooks Error H202 Occur on Windows 11?​

After upgrading to Windows 11, many users report a spike in H-series errors. That’s because:

1. Enhanced firewall settings in Windows 11 block QuickBooks ports.
2. Network Discovery and DNS resolution work differently.
3. QuickBooks Database Server Manager might not be compatible unless updated.
4. Some services like QBCFMonitorService are turned off by default.
5. Hosting settings get reset or corrupted.

So, even if QuickBooks was working fine on Windows 10, a shift to Windows 11 might re-trigger QuickBooks Error H202.

Symptoms of QuickBooks Error Code H202​

Here’s how you know you’ve hit the H202 wall:

• You can’t open the company file from a different computer.
• The system hangs when switching to multi-user mode.
• You get frequent QuickBooks freezes and lags.
• A pop-up with “Error Code H202” appears.
• Company file opens locally but not on networked workstations.

Don’t ignore these symptoms. The longer you wait, the worse the disruption gets.
