QuickBooks Error H202 occurs when QuickBooks Desktop is unable to connect to the company file stored on another computer or server in multi-user mode. This prevents workstations from accessing the company file and may display a message such as:
“Error H202: This company file is on another computer, and QuickBooks needs help connecting to it.”
Common causes include:
Incorrect hosting settings
Network connectivity problems
QuickBooks Database Server Manager issues
Firewall or security software blocking communication
Damaged or incorrect network configuration files (.ND)
Required QuickBooks services not running
The error is generally resolved by checking the network connection, verifying multi-user hosting settings, configuring firewall permissions, and running QuickBooks Database Server Manager on the server.
