What Is QuickBooks Error Code H202?

The QuickBooks Error Code H202 appears when a workstation is trying to access a company file stored on another computer (the server), but QuickBooks can’t reach the server due to communication problems.

In simple terms, QuickBooks Error H202 means your computer cannot connect to the company file hosted on the network server. This happens because of issues related to network configuration, hosting settings, or firewall restrictions.

When the error occurs, you might see a message like:

“Error Code H202: This company file is on another computer, and QuickBooks needs some help connecting.”

This error usually pops up in multi-user environments, especially when several users are trying to open the same company file simultaneously.

Common Causes of H202 Error QuickBooks

There are several technical reasons why the H202 QuickBooks Error occurs. Understanding the root cause can help you fix the issue quickly and prevent it from happening again.

Here are the most common triggers:

1. Incorrect Hosting Configuration:
   The workstation may be set to host the company file instead of the server computer, causing a connection conflict.

2. Firewall or Security Software Blocking QuickBooks:
   The Windows firewall or antivirus software may be blocking incoming or outgoing communication between QuickBooks and the server.

3. Damaged or Corrupt .ND File:
   The Network Data (.ND) file that enables QuickBooks to access company files in a network environment might be damaged or misconfigured.

4. Incorrect DNS Settings or Network Path Issues:
   QuickBooks cannot locate the IP address of the server hosting the company file.

5. QuickBooks Database Server Manager Not Running:
   If the Database Server Manager service is not active on the host computer, the connection request will fail.

6. Issues with Server Name Resolution:
   When QuickBooks cannot translate the server name into its IP address, the program fails to connect to the host.

Symptoms of QuickBooks Error H202

• Performance of QuickBooks becomes unusually slow.

• QuickBooks can’t communicate with the server hosting the company file.

If you notice any of these symptoms, you are most likely dealing with QuickBooks Error H202.
