Single networked computer receives error H202, H303, or H505 when opening the company file

When opening a company file across a network, you might see an error message that includes H202, H303, or H505. These errors occur when QuickBooks is unable to communicate with the server. To resolve this issue, ensure that all computers, including the server, are configured correctly, and then re-establish a connection.
