QuickBooks Error H202 usually occurs when a workstation cannot communicate with the computer hosting the company file in Multi-User Mode. To resolve the issue, verify that hosting is enabled on the server and that QuickBooks Database Server Manager is installed and running correctly. Check the QuickBooksDBXX and QBCFMonitorService services, review Windows Firewall permissions, and scan the company file folder using Database Server Manager. Also confirm that all workstations are connected to the same network. For assistance with QuickBooks H202 network connectivity issues, call +1(866)-513-4656.
