Key Signs You’re Dealing with Error H202

Before jumping into fixes, confirm if you’re experiencing the H202 issue. Here are the red flags:

• Error code H202 pops up while switching to multi-user mode.

• Company file fails to open in a network environment.

• QuickBooks freezes frequently.

• You get a message: "You are trying to work with a company file that is located on another computer."

What Triggers QuickBooks Error H202?

Let’s explore what causes this frustrating error:

• Incorrect Hosting Configuration: Workstations trying to host the company file.

• Blocked Ports: Windows firewall or third-party security software blocking essential QuickBooks services.

• Unavailable QuickBooks Services: Services like QBDBMgrN are not running on the server.

• Corrupt or Missing .ND File: This configuration file helps QuickBooks access files in a network.

• Network Resolution Issues: DNS problems or incorrect server names can cause communication failures.

How to Fix QuickBooks Error H202 (Step-by-Step)

Solving Error H202 involves adjusting network settings and confirming that QuickBooks services are running as expected.

1. Use the QuickBooks Tool Hub & Network Diagnostic

QuickBooks Tool Hub is your first defense.

Steps:

• Download and install QuickBooks Tool Hub.

• Open it and click on Network Issues.

• Launch the QuickBooks Database Server Manager and scan the folder containing your company file.

• Try opening the company file in multi-user mode again.

2. Ensure Proper Hosting Configuration

Only the server computer should host the company file.

To verify this:

• Go to File > Utilities in QuickBooks.

• If you see “Stop Hosting Multi-User Access” on any workstation, click it.

• Ensure the option “Host Multi-User Access” is selected only on the server.

3. Configure Windows Firewall to Allow QuickBooks Ports

Firewalls are often the invisible wall stopping QuickBooks from communicating with the server.

Add these ports as exceptions (based on your QuickBooks version):

• QuickBooks 2022: 8019, 56728, 55378-55382

• QuickBooks 2021 & earlier: Same pattern, but version-specific

4. Rename the .ND File

Damaged .ND files are a known trigger of network errors.

Steps:

• Navigate to the company file folder.

• Find and rename the file: YourCompany.qbw.nd → YourCompany.qbw.nd.old

• Restart QuickBooks Database Server Manager and rescan your company files.

If you're using an older version of QuickBooks, you might face recurring network errors. You can also consider visiting this page to upgrade quickbooks desktop to 2025, which may resolve compatibility and connection issues.

5. Check & Restart QuickBooks Services

Two essential services must be running:

• QuickBooksDBXX (where XX is your version)

• QBCFMonitorService

Steps:

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

• Find each service, right-click > Properties > Set to Automatic.

• Click Start if the service is stopped.

6. Test Network Connectivity with Ping

If you're unsure whether the workstation and server are properly connected:

• On the workstation, open Command Prompt.

• Type ping [YourServerName] and press Enter.

• Consistent replies mean good connectivity; timeouts mean network issues.

7. Add Server Info to Hosts File

How to edit:

• Navigate to C:\Windows\System32\drivers\etc.

• Open the hosts file in Notepad (as Administrator).

Save and retry accessing the company file.

Pro Tips to Prevent QuickBooks Error H202

• Regularly update QuickBooks to the latest version.

• Keep your firewall and antivirus software QuickBooks-friendly.

• Avoid altering your network configuration unnecessarily.
