What is QuickBooks Error H202?

Error H202 is part of the H-series errors (H101, H202, H303, H505) that occur when QuickBooks Desktop is set up to run in multi-user mode, but the program is unable to communicate with the server computer hosting the company file (.QBW). In simple terms, your workstation is trying to access a file stored on another computer, but the network connection is being blocked or interrupted.

When this error occurs, you may see a message like:

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

Causes of QuickBooks Error H202

Several factors can trigger QuickBooks Error H202. Understanding these causes helps you find the right fix:

1. Incorrect Hosting Configuration – The server hosting the company file is not correctly set to allow multi-user access.

2. Blocked Server Communication – The QuickBooks Database Server Manager or other essential services are blocked by Windows Firewall.

3. Damaged or Missing Network Data (.ND) File – This file helps QuickBooks identify the company file on the network. If it’s damaged, the connection fails.

4. DNS or IP Address Issues – Network settings may not be resolving the server’s IP address correctly.

5. QuickBooks Services Not Running – Services like QBCFMonitorService and QuickBooksDBXX might be stopped or disabled.

Signs and Symptoms of QuickBooks Error H202

You can identify this error by noticing one or more of the following signs:

• Error message “QuickBooks Error H202” appears on screen.

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

• Workstations cannot access the company file on the server.

• Users can open the company file in single-user mode but not in multi-user mode.

• QuickBooks Database Server Manager fails to detect the network file.

How to Fix QuickBooks Error H202

Here are the most effective solutions to resolve QuickBooks Error H202 step by step.

Solution 1: Use QuickBooks Tool Hub

The QuickBooks Tool Hub is an official utility by Intuit that helps fix common network and company file issues.
Follow these steps:

1. Close QuickBooks Desktop.

2. Download the latest version of QuickBooks Tool Hub from Intuit’s official website.

3. Install it and open the Tool Hub.

4. Go to Network Issues tab.

5. Select QuickBooks Database Server Manager.

6. Choose your company file folder and click Start Scan.

7. Once the scan completes, restart QuickBooks and open the file in multi-user mode.

This tool automatically repairs network configuration issues that cause Error H202.

Solution 2: Verify Hosting Settings

Ensure only the server computer hosts the company file.

• Open QuickBooks on each workstation.

• Go to File > Utilities.

• If you see “Host Multi-User Access,” do not click it. This means hosting is already off.

• If you see “Stop Hosting Multi-User Access,” click it to disable hosting.

• On the server, enable hosting under File > Utilities > Host Multi-User Access.

Solution 3: Add QuickBooks Services to Firewall Exceptions

Sometimes, the firewall blocks the network connection between QuickBooks and the server. To fix this:

1. Open Control Panel > Windows Defender Firewall > Advanced Settings.

2. Click Inbound Rules > New Rule.

3. Select Program, then browse to these executable files and add them one by one:

   QBW32.exe

   QBDBMgrN.exe

   QBUpdate.exe

   QBCFMonitorService.exe

4. Allow them for Private and Public networks.

5. Repeat the same under Outbound Rules.

6. Restart your computer and open QuickBooks again.

Solution 4: Rename the .ND and .TLG Files

Corrupt configuration files can prevent QuickBooks from connecting to the server.

1. Open the folder containing your company file.

2. Look for files with the same name as your company file but with extensions .ND and .TLG.

3. Right-click and rename each file, adding .old at the end (e.g., CompanyName.qbw.nd.old).

4. Open QuickBooks and try switching to multi-user mode again.

5. These files are automatically recreated when you reopen the company file.

Solution 5: Check QuickBooks Services

1. On the server computer, press Windows + R and type services.msc.

2. Locate QuickBooksDBXX (where XX represents the version year).

3. Ensure its Startup Type is set to Automatic, and the service is Running.

4. Repeat the same for QBCFMonitorService.

5. Restart both services if needed, then reopen QuickBooks.
