What Is QuickBooks Error H202?

QuickBooks Error H202 is part of the H-series errors that usually arise when a user attempts to open a company file located on another computer (server), and QuickBooks cannot reach that server due to communication issues. It signifies a multi-user setup issue and restricts access to the file.

Primary Causes of QuickBooks Error H202

Several factors may lead to this error. Understanding them helps implement the correct solution:

1. Incorrect Hosting Configuration

Only the server should host the company file. If multiple workstations have hosting turned on, it can cause network conflicts.

2. Blocked Communication Ports

QuickBooks requires specific ports to access the server. If these are blocked by your firewall, it causes the H202 error.

3. Damaged .ND File

The Network Data (.ND) file enables QuickBooks to access company files over a network. If this file is damaged, access will be restricted.

4. DNS or IP Address Issues

QuickBooks uses IP and DNS settings to locate the server. If the client cannot resolve the server name, the connection will fail.

5. QuickBooks Services Not Running

Essential services like QuickBooksDBXX and QBCFMonitor are required for multi-user mode. If they’re disabled or stopped, error H202 appears.

How to Fix QuickBooks Error H202: Step-by-Step

Let’s dive into practical fixes that help you resolve this issue and restore multi-user access.

Fix 1: Use QuickBooks Database Server Manager

1. Download and install QuickBooks Database Server Manager on the server.
2. Open the program and scan the folder where your company file is stored.
3. After scanning, reopen QuickBooks in multi-user mode.

 This tool configures firewall permissions and ensures proper communication between server and workstations.

Fix 2: Check Hosting Settings on All Systems

1. Open QuickBooks on each workstation.
2. Go to File > Utilities.
3. If you see “Host Multi-User Access”, do nothing.
4. If you see “Stop Hosting Multi-User Access”, click to disable it.

 Only the server should host; this avoids internal network conflict.

Fix 3: Rename the .ND File

1. Open the folder containing your company file.
2. Locate the file with the extension .ND (e.g., CompanyName.qbw.nd).
3. Right-click and rename it (e.g., CompanyName.qbw.nd.old).
4. Reopen QuickBooks and try accessing the company file.

 QuickBooks auto-creates a new .ND file when you reopen the file.

Fix 4: Verify QuickBooks Services

1. Press Windows + R, type services.msc, and press Enter.
2. Locate and ensure the following are Running and set to Automatic:

• QuickBooksDBXX
• QBCFMonitorService

1. Restart the services if needed.

 These services must be active for QuickBooks networking to function.

Fix 5: Manually Configure Firewall and Ports

1. Go to Windows Defender Firewall > Advanced Settings.
2. Add inbound and outbound rules for the following ports:

• QuickBooks 2024: 8019, 56728, 55378-55382

1. Save changes and restart your computer.

 This ensures that your firewall doesn’t block QuickBooks network communication.

Advanced Troubleshooting
