On a multi-user network, QuickBooks company files (QBW) are stored on a server computer. All other computers connected to the network (that don’t host the QBW files) are called workstations. When a workstation fails to access a company file placed on another computer, it results in
QuickBooks error code H202.
What causes QuickBooks Error H202?
QuickBooks error code H202 occurs when QuickBooks Desktop is trying to establish a connection to the company file, but can’t communicate with the server due to one of the following reasons:
Incorrect hosting configuration settings.
The server computer firewall is blocking incoming and outgoing communication.
Conflict with DNS server.
QuickBooks is unable to get the IP address of the host system or server hosting the company file.
Some internal QuickBooks services like QuickBooksDBXX or QBCFMonitor aren’t running on the server computer.
The network data file (.ND) is corrupt or damaged.
