Understanding QuickBooks Error H202

Error H202 is part of a series of QuickBooks errors (H101, H202, H303, and H505) that signify problems in multi-user environments. Specifically, H202 indicates that the QuickBooks software is unable to establish a connection with the company file on another computer.

Causes of QuickBooks Error H202

Hosting Configuration Issues: QuickBooks requires the Host Computer to manage multi-user access to the company file. Error H202 can occur when the Host Computer is unable to communicate with other workstations due to incorrect hosting settings.

QuickBooks Services: The QuickBooks Database Server Manager and QuickBooks Services need to run properly on the Host Computer. If these services are not functioning, Error H202 may occur.

Damaged Company File: A damaged or corrupted company file can trigger various errors, including Error H202.
