So, continue reading for valuable insights and guidance on resolving this error.

What Causes QuickBooks Error H202?

QuickBooks Error H202 is a common issue faced by users when trying to switch from single-user mode to multi-user mode. This error typically indicates that the multi-user setup is blocked, meaning QuickBooks cannot communicate with the server computer. Here’s a breakdown of the most common causes of this error:

Incorrect Hosting Configuration

The server computer, which hosts the company file, must be properly configured to allow multi-user access. If the hosting configuration is incorrect on either the server or the workstation, QuickBooks cannot connect to the server, resulting in Error H202.

Blocked Ports

QuickBooks uses specific ports to communicate over a network. If a firewall blocks these ports or not set up correctly, the communication between the QuickBooks workstation and the server is disrupted. This can lead to Error H202.

Firewall and Antivirus Issues

Firewalls and antivirus software can sometimes block the necessary communication between QuickBooks and the server. If these security programs are not properly configured to allow QuickBooks access, they can interfere with the connection and cause Error H202.

Damaged or Corrupt.ND File

The Network Data (.ND) file is crucial for QuickBooks to access company files in a network. If this file is damaged or corrupt, QuickBooks cannot locate the server, leading to Error H202.

DNS Issues

Domain Name System (DNS) problems can prevent the workstation from locating the server computer hosting the QuickBooks files. If the DNS settings are incorrect, the workstation may fail to connect to the server, resulting in Error H202.

QuickBooks Database Server Manager Issues

QuickBooks Database Server Manager helps the software communicate over a network. If this service is not running or installed correctly, QuickBooks cannot switch to multi-user mode, triggering Error H202.

IP Address Problems

Incorrect or conflicting IP addresses can cause network issues. If the server and workstation IP addresses are not properly configured, QuickBooks may fail to establish a connection, leading to Error H202.

How to Fix QuickBooks Error H202

Check Hosting Settings

Ensure that the server computer is set to host multi-user access and that no other computer in the network is set as the host.

Open Required Ports

Configure your firewall and router to allow QuickBooks to use the necessary ports. QuickBooks Desktop uses different ports for different versions, so make sure to open the correct ones.

Adjust Firewall and Antivirus Settings

Add QuickBooks and its ports to the exceptions list of your firewall and antivirus software to ensure they do not block the connection.

Repair.ND File

Delete and recreate the.ND file to fix any corruption issues. You can do this by using the QuickBooks Database Server Manager.

Verify DNS Settings

Check and correct your DNS settings to ensure the workstation can locate the server computer.

Restart QuickBooks Database Server Manager

Restart the QuickBooks Database Server Manager to ensure it is running correctly and facilitating the necessary network communication.

Check IP Addresses

Verify and correct the IP addresses of your server and workstations to avoid any conflicts that could hinder network communication.

By understanding these common causes and implementing the suggested fixes, you can resolve QuickBooks Error H202 and ensure smooth multi-user operation in your QuickBooks setup.
