What is QuickBooks Error H202?

QuickBooks Error H202 typically occurs when you try to open a company file located on another computer, but QuickBooks cannot reach the server (the computer hosting the file). This error prevents you from switching to multi-user mode, effectively cutting off access for multiple users in a networked setup.

You might see an error message that says:

“You are trying to work with a company file that is located on another computer, and this copy of QuickBooks cannot reach the server (H202).”

What Causes QuickBooks Error H202?

There are several potential reasons for this network error:

• Incorrect hosting configuration on the server or workstations

• Blocked ports needed for QuickBooks communication

• Disabled QuickBooks services like QBCFMonitorService or QuickBooksDBXX

• DNS server issues or incorrect network settings

• Windows firewall or third-party security software blocking access

Understanding the root cause can help you apply the right fix and prevent future errors.

Common Signs of QuickBooks Error H202

Here are a few symptoms that indicate you’re dealing with this error:

• You can’t switch to multi-user mode.

• QuickBooks freezes or runs slowly on the network.

• The application fails to open the company file located on the server.

• You receive an H202 error message during startup.

How to Fix QuickBooks Error H202 (Proven Solutions)

Let’s explore the most effective ways to fix QuickBooks Error H202 and restore seamless access to your company file across all systems.

Solution 1: Use QuickBooks Database Server Manager

The QuickBooks Database Server Manager (QBDSM) helps ensure that the database service is correctly configured for multi-user access.

Steps:

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

2. Open the Tool Hub and go to Network Issues.

3. Select QuickBooks Database Server Manager.

4. Click Start Scan to scan the folder where your company file is stored.

5. Once the scan finishes, click Close.

6. Restart QuickBooks on all systems and try switching to multi-user mode.

Solution 2: Verify Hosting Settings

Incorrect hosting configuration on workstations can trigger the H202 error.

Steps:

1. Open QuickBooks on each workstation.

2. Go to File > Utilities.

3. If you see “Host Multi-User Access”, do not click it—this means hosting is turned off (correct setting for workstations).

4. If you see “Stop Hosting Multi-User Access”, click it to disable hosting on that system.

Only the server (the computer where the company file is hosted) should have hosting enabled.

Solution 3: Configure Windows Firewall

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

Steps:

1. Open Control Panel > Windows Defender Firewall > Advanced Settings.

2. Right-click on Inbound Rules > New Rule.

3. Select Port > Next.

4. Add these port numbers:

   • QuickBooks 2022: 8019, 56728, 55378-55382

   • Adjust based on your version.

5. Select Allow the Connection > Finish.

6. Repeat the steps for Outbound Rules.

Restart your PC after configuring the firewall.

Solution 4: Ping the Server

Testing network connectivity helps rule out server access issues.

Steps:

Find the server name (host computer) by opening Command Prompt and typing: nginxCopyEdithostname

1. 
   

On each workstation, open Command Prompt and type: cssCopyEditping [servername]

2.  Example: ping ServerPC

3. If you receive timed-out replies, the workstation can’t communicate with the server—check your network and firewall.

Solution 5: Check QuickBooks Services

Ensure key services like QBCFMonitorService and QuickBooksDBXX are running on the server.

Steps:

1. Press Windows + R > type services.msc.

2. Find and double-click:

   • QuickBooksDBXX (XX depends on your version)

   • QBCFMonitorService

3. Ensure Startup Type is set to Automatic.

4. Click Start if they’re not already running.

5. Click Apply and then OK.

Solution 6: Add Server to Windows Hosts File

If DNS is not resolving correctly, adding the server IP and hostname to the hosts file may help.

Steps:

1. Open Notepad as Administrator.

2. Navigate to: C:\Windows\System32\Drivers\Etc\hosts

Add a new line at the bottom: pgsqlCopyEdit[Server IP]    [Server Name]

 Example: CopyEdit192.168.1.100    ServerPC

3. 
   

4. Save the file and restart QuickBooks.

Solution 7: Use the QuickBooks Connection Diagnostic Tool

The Connection Diagnostic Tool automatically detects and resolves common network and firewall issues.

Steps:

1. Download the tool from the QuickBooks Tool Hub.

2. Go to Network Issues > Connection Diagnostic Tool.

3. Select your company file and run diagnostics.

4. Follow the on-screen instructions to fix any detected problems.
