What is QuickBooks Error H202?

QuickBooks Error H202 occurs when QuickBooks fails to communicate with the server hosting the company file in multi-user mode. This prevents users from accessing the file, leading to workflow disruptions.

What Causes QuickBooks Error H202?

This error is typically triggered by network configuration issues or communication failures between the host system and workstations. Some common causes include:

Incorrect Hosting Configuration – QuickBooks is not properly set up for multi-user mode.
Blocked Communication by Firewall – Windows Firewall or third-party security software is blocking QuickBooks.
Incorrect DNS Settings – Improper DNS configurations prevent QuickBooks from connecting to the server.
QuickBooks Database Server Manager Issues – If this tool is not running, workstations cannot access the company file.
Damaged or Corrupt Network Data (.ND) File – A corrupted .ND file can prevent QuickBooks from recognizing the network path.
Server Not Running Properly – If the hosting server is turned off or experiencing issues, workstations won’t connect.

How to Fix QuickBooks Error H202?

Follow these step-by-step solutions to fix Error H202 and restore multi-user functionality:

1. Run QuickBooks Database Server Manager

Open QuickBooks Tool Hub (download from the Intuit website if needed).
Select Network Issues and open QuickBooks Database Server Manager.
Click Browse and select the folder where the company file is stored.
Click Start Scan and let the tool fix any detected issues.

2. Check Hosting Settings on Each Workstation

Open QuickBooks on each workstation.
Go to File > Utilities.
If you see Host Multi-User Access, do not select it (this means hosting is not enabled).
If you see Stop Hosting Multi-User Access, select it to disable hosting on that workstation.
Repeat on all workstations except the main server.

3. Add QuickBooks to Windows Firewall Exceptions

Open Windows Defender Firewall.
Click Advanced Settings > Inbound Rules > New Rule.
Select Program, then browse to QuickBooks executable files (QBDBMgrN.exe, QBW32.exe).
Allow all connections, then repeat for Outbound Rules.
Restart QuickBooks and check if the issue is resolved.

4. Verify & Update DNS Settings

Press Windows + R, type cmd, and hit Enter.
Type ipconfig /flushdns and press Enter to clear the DNS cache.
Restart your computer and retry accessing QuickBooks in multi-user mode.

5. Repair the QuickBooks Network Data (.ND) File

Open the folder containing your QuickBooks company file.
Locate the .ND file (e.g., CompanyFile.qbw.nd).
Right-click and rename the file by adding .old at the end (CompanyFile.qbw.nd.old).
Restart QuickBooks and let it create a new .ND file.

6. Test Network Connectivity

Open Command Prompt on a workstation.
Type ping [Server Name] (replace [Server Name] with your actual server name) and press Enter.
If there is no response, check your network connection and firewall settings.

7. Restart QuickBooks Services on the Server

Press Windows + R, type services.msc, and hit Enter.
Find QuickBooksDBXX (XX represents your QuickBooks version).
Right-click, select Restart, and do the same for QBCFMonitorService.

Preventing QuickBooks Error H202

To avoid facing Error H202 again, follow these best practices:

Ensure Proper Hosting Configuration

A strong and stable network ensures smooth multi-user access. Avoid using public or unreliable networks.

Regularly Scan & Repair Network Issues
