QuickBooks is a powerful accounting tool, especially in multi-user mode, which allows multiple team members to collaborate on company files. However, one common roadblock users encounter is QuickBooks Error Code H202. This error typically appears when a user tries to open a company file stored on another computer, and QuickBooks cannot reach the server hosting the file.

This issue disrupts workflow and productivity, especially in a networked environment. Fortunately, there are proven ways to fix it. This step-by-step guide will help you resolve QuickBooks Error H202 quickly and restore smooth access in multi-user mode.

What is QuickBooks Error Code H202?

QuickBooks Error Code H202 occurs when the software tries to establish a connection to the company file in multi-user mode, but the connection is blocked. The error message usually reads:

"This company file is on another computer, and QuickBooks needs some help connecting."

This means QuickBooks is unable to communicate with the server due to incorrect hosting settings, firewall blocks, or network configuration issues.

Common Causes of Error Code H202

Understanding the root cause helps in applying the correct fix. Common reasons include:

• QuickBooks can’t locate the server (host computer).
  
  

• Hosting settings are incorrect.
  
  

• The QuickBooks Database Server Manager is not running.
  
  

• The firewall or antivirus is blocking communication.
  
  

• DNS server issues or wrong IP address.
  
  

• Damaged or misconfigured .ND file (Network Descriptor file).
  
  

Step-by-Step Guide to Fix QuickBooks Error Code H202

Here’s how to troubleshoot and resolve the issue:

Step 1: Verify Hosting Settings

Ensure only the server (host) computer has hosting enabled.

On each workstation:

1. Open QuickBooks and go to File > Utilities.
   
   

2. If you see Host Multi-User Access, do not click it (this means the computer is not hosting).
   
   

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

Only the server should have hosting enabled. All other workstations should have it turned off.

Step 2: Use QuickBooks File Doctor Tool

QuickBooks File Doctor automatically detects and fixes H-series errors.

1. Download and install the QuickBooks Tool Hub from the official Intuit website.
   
   

2. Open the Tool Hub and select Company File Issues.
   
   

3. Click Run QuickBooks File Doctor.
   
   

4. Select your company file from the list or browse manually.
   
   

5. Choose Check your file and network and click Continue.
   
   

6. Enter your QuickBooks admin credentials and wait for the scan to complete.
   
   

This tool fixes network-related problems and can automatically repair minor file damage.

Step 3: Check and Configure Firewall Settings

Your firewall might be blocking QuickBooks from communicating over the network.

1. Go to Control Panel > Windows Defender Firewall > Advanced Settings.
   
   

2. Add Inbound and Outbound Rules for the following QuickBooks ports (based on your version):
   
   

   • QuickBooks 2024: 8019, 56728, 55378–55382
     
     

   • QuickBooks 2023: 8019, 56727, 55373–55377
     
     

   • (adjust for your version as needed)
     
     

3. Allow QuickBooks applications (e.g., QBDBMgrN.exe, QBW32.exe) through the firewall.
   
   

After adding the rules, restart QuickBooks and check if the error persists.

Step 4: Ping the Server to Test Network Connection

1. On the workstation, open Command Prompt (CMD).
   
   

2. Type ping [ServerName] (replace with the actual server name).
   
   

3. If you receive a reply, the server is reachable. If not, there is a network issue.
   
   

Also, make sure all computers are on the same network and have a stable internet connection.

Step 5: Rename the .ND File

The .ND file stores network configuration info. If it's corrupted, QuickBooks can’t connect.

1. Navigate to the folder containing your company file.
   
   

2. Find the file with the same name as your company file but ending in .ND.
   
   

3. Right-click and select Rename.
   
   

4. Add .OLD at the end (e.g., CompanyFile.qbw.nd.old).
   
   

5. Open QuickBooks and re-scan the folder using the QuickBooks Database Server Manager.
   
   

Step 6: Use QuickBooks Database Server Manager

Ensure the Database Server Manager is running properly.

1. Open QuickBooks Tool Hub > Network Issues.
   
   

2. Select QuickBooks Database Server Manager.
   
   

3. Click Browse and select the folder containing your company file.
   
   

4. Click Start Scan.
   
   

5. Once complete, recheck multi-user access.
   
   

This step refreshes your network connection and re-establishes the multi-user setup.

Step 7: Restart QuickBooks Services

Sometimes, a service may stop running on the server.

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

2. Find and restart the following services:
   
   

   • QuickBooksDBXX (XX is your version, like 33 for 2023)
     
     

   • QBCFMonitorService
     
     

Ensure both are set to Automatic startup.
