How to Fix QuickBooks Error H202 (Proven Solutions)

Solution 1: Use the QuickBooks Tool Hub

1. Download and install the QuickBooks Tool Hub.

2. Open the tool and go to the Network Issues tab.

3. Select QuickBooks Database Server Manager and scan the folder containing your company file.

4. Once the scan is complete, try reopening the company file in multi-user mode.

This built-in tool detects and resolves network configuration issues automatically.

Solution 2: Check and Configure Hosting Settings

1. On all workstations, open QuickBooks and go to File > Utilities.

2. If you see Host Multi-User Access, leave it as-is.

3. If you see Stop Hosting Multi-User Access, click it to disable hosting on workstations.

Note: Only the server should host the company file.

Solution 3: Verify QuickBooks Services

1. Press Windows + R, type services.msc, and press Enter.

2. Look for QuickBooksDBXX and QBCFMonitorService.

3. Right-click each and select Start (if not already running).

4. Set both to Automatic startup type.

Solution 4: Open Network Ports Manually

Make sure the following ports are open in your firewall:

• QuickBooks 2022: 8019, 56728, 55378-55382

• QuickBooks 2021: 8019, 56727, 55373-55377

• Add exceptions for QBDBMgrN.exe and QBCFMonitorService.exe

Adjusting firewall settings ensures uninterrupted communication between systems.

Solution 5: Rename the .ND File

1. Go to the folder containing your company file.

2. Look for a file with the same name as your company file but with a .ND extension.

3. Rename it (e.g., CompanyFile.nd.old).

4. Reopen QuickBooks and rescan the folder using QuickBooks Database Server Manager.

A fresh .ND file is generated automatically when you rescan the folder, resolving file corruption.
