What is QuickBooks Error H202?

Common Causes of QuickBooks Error H202

Here are the most common reasons you might see Error H202 in QuickBooks Desktop:

1. Incorrect hosting configuration

2. QuickBooks services like QBCFMonitorService or QuickBooksDBXX are not running

3. Windows Firewall or third-party security software is blocking access

4. DNS server not resolving the server name

5. Damaged or misconfigured .ND file

6. QuickBooks Database Server Manager not installed on the host

Relation to QuickBooks Error 40003

Though not directly related, QuickBooks Error 40003 is another connectivity-related error that appears during payroll updates or communication with Intuit servers.
