What is QuickBooks Error H202?

QuickBooks Error H202 generally appears when a user attempts to switch to multi-user mode and QuickBooks cannot communicate with the server. The full error message might read:

“You are trying to work with a company file that is located on another computer, and this copy of QuickBooks cannot reach the server on that computer.”

This error is a part of the H-series (H101, H202, H303, H505), which is related to multi-user mode connectivity issues.



Common Causes of QuickBooks Error H202

To resolve QuickBooks Error H202 efficiently, it’s essential to understand the underlying reasons. Some of the most frequent causes include:

  • Incorrect hosting configuration settings

  • Blocked communication by firewall or security software

  • Damaged or incorrect DNS settings

  • QuickBooks services (QBCFMonitor and QuickBooksDBXX) not running

  • Issues with the .ND file

  • QuickBooks Database Server not installed on the server



How to Troubleshoot QuickBooks Error H202 Like a Pro

Here’s a comprehensive, step-by-step approach to troubleshoot and fix QuickBooks Error H202.



Step 1: Use QuickBooks Tool Hub

Intuit has developed a dedicated tool called the QuickBooks Tool Hub that can diagnose and fix many common errors.

Download & Use QuickBooks Tool Hub

  1. Close QuickBooks.

  2. Download the Tool Hub from Intuit's official website.

  3. Install and open it.

  4. Go to the Network Issues tab.

  5. Click on QuickBooks Database Server Manager.

  6. Scan the folder where your company file is located.

  7. Restart QuickBooks and try switching to multi-user mode.

Step 2: Verify Hosting Settings

Make sure only the server computer is hosting the company file.

On Each Workstation:

  1. Open QuickBooks.

  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 it.

This ensures only the server is the host, avoiding conflicts.



Step 3: Ping the Server

Check if your workstation can communicate with the server via its IP address.

How to Ping the Server:

  1. On the workstation, press Windows + R, type cmd, and press Enter.

  2. Type ping [Server Name] and press Enter.

If you get a slow or lost packet response, it indicates connectivity issues.



Step 4: Configure Windows Firewall Settings

Incorrect firewall settings can block communication between QuickBooks and the server.

Open Required Ports:

Ensure the following ports are open for QuickBooks Desktop:

  • QuickBooks 2024: 8019, 56728, 55378–55382

  • QuickBooks 2023: 8019, 56727, 55373–55377

  • (Adjust port numbers based on your QuickBooks version)

You can manually configure the firewall or let the QuickBooks File Doctor tool do it.



Step 5: Check QuickBooks Services

Ensure that QuickBooksDBXX and QBCFMonitorService are running on the server.

Steps:

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

  2. Locate QuickBooksDBXX and QBCFMonitorService.

  3. Right-click each and choose Start if they are not running.

  4. Set Startup Type to Automatic.



Step 6: Rename the .ND File

The .ND (Network Descriptor) file helps QuickBooks access the company file in a network. A corrupted .ND file can cause Error H202.

Steps:

  1. Open the folder containing your company file.

  2. Find the file with a .ND extension (e.g., companyfile.qbw.nd).

  3. Right-click it and rename to companyfile.qbw.nd.old.

  4. Reopen QuickBooks and rescan the file using the Tool Hub.



Step 7: Add Server to Windows Hosts File

Manually adding the server IP and name to the hosts file on each workstation can resolve DNS-related issues.

Steps:

  1. Go to: C:\Windows\System32\Drivers\Etc

  2. Open hosts file with Notepad (Run as Administrator).

  3.  Add this line at the bottom: CopyEdit192.168.1.XX ServerName


  1. Save and close the file.



Step 8: Install QuickBooks Database Server Manager on the Server

The Database Server Manager enables file hosting for multi-user mode. If it's not installed, QuickBooks Error H202 is likely.

Download it from the Tool Hub or Intuit’s website and install it only on the server computer.
