Understanding QuickBooks Error H202

What is QuickBooks Error H202?

QuickBooks Error H202 is a multi-user mode error that occurs when QuickBooks Desktop is unable to communicate with the company file located on another computer (server). When this error appears, users cannot access the company file in multi-user mode, and the following error message may be displayed:

  • “Error H202: This company file is on another computer, and QuickBooks needs some help connecting.”

This error indicates that QuickBooks is unable to establish a connection with the server hosting the company file.

Symptoms of QuickBooks Error H202

  • Multi-User Mode Failure: Users are unable to switch to or work in multi-user mode.
  • Error Message: The error code H202 appears on the screen when trying to access the company file.
  • Performance Issues: The system may experience slow performance or hang when attempting to open the company file.
  • Communication Breakdown: QuickBooks cannot communicate with the server or the computer hosting the company file.

Causes of QuickBooks Error H202

Network Configuration Issues

  • Incorrect Hosting Configuration: The hosting settings may be improperly configured, preventing QuickBooks from connecting to the server.
  • Blocked Ports: QuickBooks requires specific ports to communicate with the server. If these ports are blocked by the firewall, Error H202 may occur.
  • Damaged .ND File: The .ND (Network Data) file is crucial for QuickBooks to locate the company file on the network. If this file is damaged or corrupted, QuickBooks may not be able to connect to the company file.

Server and DNS Problems

  • Server Down: The server hosting the QuickBooks company file might be turned off or experiencing issues, preventing access to the file.
  • Incorrect DNS Settings: Improperly configured DNS settings can result in communication errors between QuickBooks and the server.

QuickBooks Database Server Manager Issues

  • Database Server Manager Not Running: QuickBooks Database Server Manager is necessary for hosting multi-user mode. If it is not running, users may encounter Error H202.
  • Outdated QuickBooks: Using an outdated version of QuickBooks may result in compatibility issues, leading to multi-user mode errors.

How to Fix QuickBooks Error H202

Step 1: Verify Network Connectivity

  1. Ping the Server: Ensure that the workstation can communicate with the server by pinging the server from the workstation.
    • Press Windows + R to open the Run dialog.
    • Type cmd and press Enter.
    • Type ping [ServerName] and press Enter. Replace [ServerName] with the name of your server.
    • If you receive a response, the connection is active; if not, there is a network connectivity issue.
  2. Check Network Cables: Ensure that all network cables are securely connected and functioning properly.

Step 2: Check Hosting Settings

  1. Access QuickBooks: Open QuickBooks on all workstations.
  2. Go to File Menu: Click on the File menu and select Utilities.
  3. Check Hosting: If you see the option Host Multi-User Access, it means that hosting is disabled on that workstation. If you see Stop Hosting Multi-User Access, select it to disable hosting on the workstation.
  4. Enable Hosting on Server: Ensure that hosting is enabled only on the server where the company file is stored.

    • QuickBooks 2020: Port 8019, 56727, 55373-55377

Step 4: Use QuickBooks File Doctor

  1. Download QuickBooks Tool Hub: Download and install the QuickBooks Tool Hub from the official Intuit website.
  2. Run QuickBooks File Doctor: Open the Tool Hub and select Company File Issues. Click on Run QuickBooks File Doctor.
  3. Select Company File: Choose the company file and select Check your file. The tool will diagnose and repair any network and company file issues.
  4. Retry Accessing the File: After the repair is complete, try accessing the company file in multi-user mode.

Step 5: Recreate the .ND File

  1. Locate .ND File: Navigate to the folder containing your QuickBooks company file.
  2. Rename the .ND File: Right-click on the .ND file (e.g., CompanyFileName.qbw.nd) and select Rename. Add .old to the end of the file name (e.g., CompanyFileName.qbw.nd.old).
  3. Restart QuickBooks Database Server Manager: Go to Start > Programs > QuickBooks > QuickBooks Database Server Manager. Select Scan Folders and add the folder containing the company file. This will recreate the .ND file.
  4. Attempt Multi-User Mode Again: Open QuickBooks and attempt to switch to multi-user mode.

Step 6: Restart QuickBooks Database Server Manager

  1. Open Services: Press Windows + R, type services.msc, and press Enter.
  2. Locate QuickBooksDBXX: Find QuickBooksDBXX (where XX represents your QuickBooks version) in the list.
  3. Restart the Service: Right-click on QuickBooksDBXX and select Restart.
  4. Check Multi-User Mode: After restarting, check if QuickBooks can connect to the company file in multi-user mode.
