Causes of QuickBooks H202 Company File Errors

Here are the most common reasons for seeing the QuickBooks H202 Company File Errors Causes, Solutions, and Fixes message:

1. Incorrect Hosting Configuration
2. The hosting settings on one or more workstations may be incorrect, causing conflicts when QuickBooks tries to access the file in multi-user mode.
3. Firewall Blocking Communication
4. Windows Firewall or third-party security software can block QuickBooks services (QBDBMgrN, QuickBooksDBXX) from communicating on the network.
5. Damaged Network Data File (.ND)
6. A corrupt or outdated .ND file can prevent QuickBooks from connecting to the company file properly.
7. QuickBooks Database Server Not Running
8. The QBDBMgrN service may not be running on the host computer, interrupting the network connection required to access the file.
9. DNS or Network Name Resolution Issues
10. When QuickBooks cannot locate the IP address of the server using the hostname, it triggers the H202 error.

Step-by-Step Solutions to Fix Error H202 in QuickBooks Desktop

Try these troubleshooting steps in order to fix the QuickBooks H202 error and restore access to your company file.

Step 1: Verify Hosting Configuration

1. Open QuickBooks Desktop on each workstation.
2. Go to File > Utilities.
3. If you see Host Multi-User Access, do not select it (leave it unchecked).
4. If you see Stop Hosting Multi-User Access, select it to disable hosting on that workstation.

Only the server computer should host the company file.

Step 2: Run QuickBooks Database Server Manager

1. Press Windows + R, type services.msc, and press Enter.
2. Scroll down to QuickBooksDBXX (where XX is your version, e.g., QuickBooksDB30 for 2020).
3. Right-click the service and choose Start (or Restart if already running).
4. Repeat for the QBCFMonitorService.

Step 3: Configure Firewall Settings

Ensure Windows Firewall allows QuickBooks programs through:

1. Go to Control Panel > System and Security > Windows Defender Firewall.
2. Select Allow an app through Windows Firewall.
3. Add the following ports:

• QuickBooks Desktop 2021 and later: 8019, 56728, 55378-55382

1. Save the changes, and restart the computer.

Step 4: Rename the .ND File

1. Navigate to the folder containing your company file.
2. Locate the file with the same name as your company but ending in .ND (e.g., CompanyName.qbw.nd).
3. Right-click and rename it to CompanyName.qbw.nd.old.
4. Open QuickBooks Database Server Manager and rescan the folder.

This refreshes the connection path.

Step 5: Test Network Connection

1. Press Windows + R and type ping [servername], then press Enter.
2. If packets are lost or the response fails, check your network cable or router connection.
3. Ensure all computers are on the same domain or network.
