What Is QuickBooks Error H202?

QuickBooks Error H202 occurs when your company file is stored on a server computer, but QuickBooks Desktop is unable to access it. Essentially, your QuickBooks program on one system tries to connect to the company file hosted on another system, but communication breaks down.

Most often, the error message reads:
“This company file is on another computer, and QuickBooks needs some help connecting.”

This problem stops multi-user mode from functioning properly, preventing team members from accessing the company file. Understanding the underlying causes helps you fix QuickBooks Error H202 efficiently.

Why Does QuickBooks Error Code H202 Occur?

A few common reasons trigger QuickBooks H202 error, including network and configuration issues. Here’s what may be happening behind the scenes:

  1. Incorrect hosting configuration — The hosting setting might be turned on for multiple systems instead of only the server.

  2. Blocked communication ports — QuickBooks requires open firewall ports for data sharing. Closed ports can block connection requests.

  3. Damaged or misconfigured DNS settings — Wrong network resolutions can prevent the workstation from finding the correct server location.

  4. QuickBooks Database Server Manager not running — If this service stops, workstations can’t connect to the multi-user file.

  5. Missing or damaged Network Data (.ND) file — This small file helps QuickBooks identify networked company files; if corrupt, it hinders access.

When any of these conditions exist, the workstation fails to connect, triggering QuickBooks Desktop Error H202.

How to Fix QuickBooks Error H202

Let’s look at some proven methods to resolve the problem effectively. Try them in order for best results.

1. Verify Hosting Settings

Ensure that hosting is enabled only on the server system.

  • On each workstation, open QuickBooks and go to File > Utilities.

  • If you see Stop Hosting Multi-User Access, select it to disable hosting on that computer.

  • Only the server computer should display Host Multi-User Access as active.

This simple check often helps you fix QuickBooks H202 instantly.

2. Use QuickBooks Database Server Manager

Run QuickBooks Database Server Manager to scan your company files and refresh the network connection.

  • Go to the Start Menu > QuickBooks Tools Hub > Network Issues tab.

  • Select QuickBooks Database Server Manager.

  • Choose the folder containing your company file and click Start Scan.

  • After the scan, open QuickBooks again in multi-user mode.

3. Test Network Connectivity

You can test if the affected workstation communicates properly with the server.

  • Press Windows + R, type ping [servername], and press Enter.

  • If replies are inconsistent or timed out, there’s a network communication problem.

  • Restart both systems and verify the firewall’s inbound/outbound settings.

Ensuring a stable connection between systems is crucial to fix QuickBooks Error H202 permanently.

4. Configure Firewall and Ports

QuickBooks uses specific ports to function seamlessly. Make sure your firewall isn’t blocking them.

  • Open your security software or firewall settings.

  • Add exceptions for QuickBooks and ports: 8019, 56728, 55378–55382.

  • Apply the changes and restart QuickBooks.

If you’re unsure how to handle firewall rules safely, reach out to trained professionals at +1-866-408-0444 for guidance.

5. Edit the Windows Hosts File

Sometimes QuickBooks cannot identify the server because of incorrect IP mapping. Editing the hosts file can fix this.

  • Locate the hosts file in C:\Windows\System32\Drivers\Etc.

  • Add the server’s IP address along with its computer name.

  • Save the file and restart QuickBooks.

Once you reopen the software, check if the QuickBooks H202 error is gone.

6. Rename the .ND File

Damaged network data files can cause communication failures.

  • Go to the folder containing your company file.

  • Find the file ending in .ND (for example, CompanyFileName.qbw.ND).

  • Right-click and rename it to CompanyFileName.qbw.ND.old.

  • Reopen QuickBooks and allow it to automatically recreate a new .ND file.

This often clears up QuickBooks Desktop Error H202 in minutes.
