QuickBooks, developed by Intuit, is a widely used accounting software designed to streamline financial management for businesses. While QuickBooks is renowned for its efficiency and user-friendly interface, users sometimes encounter issues, especially in multi-user hosting environments. One common problem is Error Code H202, which indicates a connectivity issue between the QuickBooks Company file and the server. This article aims to provide a comprehensive guide to understanding, diagnosing, and resolving Error Code H202.
Understanding Error Code H202
Error Code H202 typically arises when a QuickBooks user attempts to switch to multi-user mode and the software cannot access the company file located on another computer (server). This error message implies that QuickBooks cannot establish a stable connection to the server hosting the company file. The primary causes of this error include:
- Network Connectivity Issues: The network setup may be preventing QuickBooks from communicating with the server.
- Incorrect Hosting Configuration: QuickBooks might not be properly configured for multi-user hosting on the server.
- Firewall Settings: Firewall or security software on the server or workstation may be blocking communication.
- DNS Server Issues: Problems with the DNS server can prevent the workstation from finding the server.
- Corrupt or Damaged .ND File: The .ND (Network Data) file associated with the QuickBooks company file might be damaged.
Symptoms of Error Code H202
When encountering Error Code H202, users typically experience the following symptoms:
- QuickBooks fails to switch to multi-user mode.
- An error message appears: "Error H202: This company file is on another computer, and QuickBooks needs some help connecting."
- The QuickBooks application becomes unresponsive or lags.
Diagnosing Error Code H202
Step 1: Check Network Connectivity
Ensure that the network is functioning correctly and all computers are connected. You can test the network connection by:
1. Pinging the server from a workstation:
- Open the Command Prompt.
- Type ping [Server Name] and press Enter.
- If you receive a response, the network connection is active.
Step 2: Verify Hosting Settings
Confirm that the server is set to host multi-user access and the workstations are not:
- Open QuickBooks on the server.
- Go to File > Utilities.
- Ensure that Host Multi-User Access is selected on the server.
- On the workstations, ensure Stop Hosting Multi-User Access is selected.
Step 3: Use QuickBooks File Doctor
QuickBooks File Doctor is a tool designed to fix common network and company file issues:
- Download and install QuickBooks File Doctor from the official Intuit website.
- Run the tool and select the company file.
- Follow the on-screen instructions to diagnose and fix the error.
Step 4: Check Firewall and Security Settings
Firewall or security software might be blocking communication between QuickBooks and the server. Ensure that the necessary ports are open:
- Open the Control Panel on the server.
- Go to System and Security > Windows Defender Firewall.
- Select Advanced Settings.
- Create a new inbound rule to open the following ports:
- Repeat the process for outbound rules.
Step 5: Verify DNS Settings
Ensure that the DNS settings are correct to allow proper communication between the server and workstations:
- Open the Command Prompt.
- Type ipconfig /all and press Enter.
- Note the IP address of the server.
- Ensure that the workstations are using the same DNS server as the server.
Step 6: Repair the .ND File
The .ND file enables QuickBooks to access the company file over the network. A damaged .ND file can cause Error Code H202:
- Locate the company file folder.
- Find the file with the .ND extension (e.g., Company File. qb w.nd).
- Rename the file by adding .old to the end (e.g., Company File. Qbw.nd.old).
- Open QuickBooks and rescan the company file using the Database Server Manager:
- Open the QuickBooks Database Server Manager from the Start menu.
- Click Add Folder and browse to the location of the company file.
- Click Scan.
Advanced Troubleshooting
- Use QuickBooks Database Server Manager
- The QuickBooks Database Server Manager helps configure QuickBooks for multi-user access:
- Open the QuickBooks Database Server Manager.
- Click Scan Folders.
- Select the folder containing the QuickBooks company file and click Scan.
- Ensure that the company file is listed under the Folders that contain QuickBooks company files section.
Restart QuickBooks Services
Restarting QuickBooks services can resolve connectivity issues:
- Press Windows + R, type services.msc, and press Enter.
- Locate the following services:
- QuickBooksDBXX (XX represents the version of QuickBooks)

- Right-click each service and select Restart.
Edit Windows Hosts File
Editing the Windows Hosts file can resolve DNS-related issues:
- Navigate to C: \Windows\System32\Drivers\etc.
