This error typically arises in multi-user mode and can halt your operations if not addressed promptly.

In this detailed guide, we’ll explain what QuickBooks Error H202 is, what causes it, and how you can fix it using proven solutions — including the QuickBooks Tool Hub. By the end of this article, you'll be equipped with all the information you need to resolve this error and prevent it in the future.

What is QuickBooks Error H202?

QuickBooks Error H202 occurs when you attempt to switch to multi-user mode, but QuickBooks fails to connect to the server that hosts the company file (.QBW). It means the software cannot reach the server computer due to network issues or improper setup.

Error Message Example: “Error code H202: This company file is on another computer, and QuickBooks needs help connecting.”

This problem prevents multiple users from accessing the company file located on a different system, thereby disrupting collaborative work in a multi-user environment.

Common Causes of QuickBooks Error H202

There are several reasons why QuickBooks Error H202 may appear, including:

1. Incorrect hosting configuration settings

2. QuickBooks services (like QBCFMonitor or QuickBooksDBXX) are not running

3. Blocked communication by firewall or security software

4. Damaged or incorrect .ND file

5. Issues with DNS or network resolution

6. QuickBooks Database Server Manager is not installed on the server

Understanding these causes will help you implement the most effective solution for your scenario.

Symptoms of QuickBooks Error H202

• QuickBooks freezes or becomes slow when switching to multi-user mode

• You see the H202 error message on screen

• You’re unable to open the company file stored on the server

• QuickBooks crashes while accessing the network file

• Inability to use multi-user mode

Solution 2: Check QuickBooks Hosting Settings

Make sure hosting is enabled only on the server and disabled on all workstations.

Steps:

1. On each workstation (excluding server), open QuickBooks.

2. Go to File > Utilities.

3. If you see “Host Multi-User Access”, do nothing.

4. If you see “Stop Hosting Multi-User Access”, click it.

Only the server should have hosting turned on.

Solution 3: Restart QuickBooks Database Server Manager

QuickBooks Error H202 may be caused by the database server not running properly.

Steps:

1. Press Windows + R, type services.msc, and hit Enter.

2. Locate and restart the following services:

   • QuickBooksDBXX (where XX is your QuickBooks version)

   • QBCFMonitorService

3. Right-click and choose Restart. Ensure startup type is set to Automatic.

Solution 4: Configure Firewall and Antivirus Settings

Your firewall or antivirus may block communication between QuickBooks and the server.

Steps:

1. Open Control Panel > System and Security > Windows Defender Firewall.

2. Click on Allow an app through Windows Firewall.

3. Ensure the following ports are open:

   • QuickBooks 2024: 8019, 56728, 55378–55382

   • Add rules for both inbound and outbound connections.

4. Save settings and restart your system.

You may also temporarily disable third-party antivirus software for testing.

Solution 5: Rename the .ND File

The .ND file helps QuickBooks access the company file over the network. A damaged .ND file can trigger Error H202.

Steps:

1. Go to the folder where your company file is stored.

2. Locate the file with a .ND extension (e.g., CompanyFile.qbw.nd).

3. Right-click > Rename > add .old to the end.

   • Example: CompanyFile.qbw.nd.old

4. Open QuickBooks and try accessing the company file again.

Solution 6: Ping the Server from Workstation

Network connectivity issues can also lead to Error H202.

Steps:

1. Find your server computer's name (from system properties).

2. On the workstation, press Windows + R, type cmd and press Enter.

In the command window, type: pgsqlCopyEditping [server name]

3.  Example: ping Server01

If the ping fails or has packet loss, troubleshoot network connectivity or consult your IT team.

Solution 7: Add Server to Windows Hosts File

Sometimes DNS misconfiguration causes Error H202. Manually updating the hosts file can help.

Steps:

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

2. Right-click on hosts file > Open with Notepad.

Add your server IP and name at the end of the file. Example: CopyEdit192.168.1.101   Server01

3. 
   

4. Save and exit. Try reopening QuickBooks.

Solution 8: Reinstall QuickBooks in Multi-User Mode

If none of the above methods work, you may need to reinstall QuickBooks on all workstations and the server.

1. Backup your company files.

2. Uninstall QuickBooks from all systems.

3. Reinstall with multi-user setup selected.

4. Restore the company file and recheck for Error H202.
