What is QuickBooks Error Code H202, and How Do You Fix It?

When switching QuickBooks to multi-user mode, users often report receiving error code H202 in QuickBooks. This error usually means that multi-user connection to your server computer, used for storing QuickBooks company files (QBW), is blocked. Inability to communicate with the server computer will prevent you from accessing the QuickBooks company file.

What is QuickBooks Error H202? 

On a multi-user network, QuickBooks company files (QBW) are stored on a server computer. All other computers connected to the network (that don’t host the QBW files) are called workstations. When a workstation fails to access a company file placed on another computer, it results in H202 QuickBooks error. The error message reads as follows:

Error code: H202

This company file is on another computer, and QuickBooks needs some help connecting.

Here’s how to fix this problem:
On the computer where the company file is located, open the start menu, then open QuickBooks Database Server Manager. The Database Server Manager will scan your files and restore the connection.

What Causes QuickBooks Error H202?

QuickBooks error code H202 occurs when QuickBooks Desktop is trying to establish a connection to the company file, but can’t communicate with the server due to one of the following reasons:

• Incorrect hosting configuration settings.
• The server computer firewall is blocking incoming and outgoing communication.
• Conflict with DNS server.
• QuickBooks is unable to get the IP address of the host system or server hosting the company file.
• Some internal QuickBooks services like QuickBooksDBXX or QBCFMonitor aren’t running on the server computer.
• The network data file (.ND) is corrupt or damaged.

How to Fix QuickBooks Error H202?

NOTE: Before performing the solutions explained in this section, make sure to back up your QBW file. Doing so will ensure that you can go back and restore the original data.

Intuit recommends using the QuickBooks Database Server Manager to fix the error. But if you’ve already done that, and still getting H202 error, try the following solutions:

NOTE: For optimum results, implement the solutions in the following order.

Solution 1 – Test Network Connectivity

Ping your server from the workstation getting error H202 to check network connection.

NOTE: If you don’t know your server name, you will need to turn on “Network Discovery” on your server computer and any workstation receiving the error.

Follow these steps to ping your server:

• Type run into Windows search bar to open Run window.

Solution 3 – Configure your Firewall Settings for QuickBooks Desktop

Make sure that the server computer firewall settings isn’t blocking QuickBooks. Read the post ‘Configure Firewall and Internet security settings for QuickBooks Desktop’ for detailed instructions on adding QuickBooks ports exception on the firewall.

Repeat the steps for QBCFMonitorService. Once you’ve completed the steps, open QuickBooks on each workstation. Click the File menu and choose Switch to Multi-user Mode option. If you can correctly open everything, the problem is fixed.

Solution 5 – Add your Server to Windows Hosts File

To add your computer server to the Windows hosts file, you will need to edit the file. To do so, follow these steps:

C:\Windows\System32\Drivers\Etc.

C:\Windows\Syswow64\Drivers\Etc.
