Methods to Resolve QuickBooks Error Code H303
Now that we've identified the causes, let's explore solutions. Here are two straightforward approaches to eliminate error H303:
First Solution: Disable the Host Multi-User Access Feature
Error H303 typically indicates that QuickBooks is running on one or more workstations. Only the server should be configured for multi-user mode. Workstations should not host company files; therefore, the Host Multi-User Access option must be disabled.
· Launch QuickBooks on any system experiencing the H303 error.
· Close the company files and navigate to File > Utilities.
· If the Host Multi-User Access option is visible, do not select it. Proceed to the next workstation. This one isn't causing the issue.
· If the "Stop Hosting Multi-User Access" option is available, select it.
· Repeat these steps on each workstation encountering Error H303.
· Before proceeding to the server computer, verify the workstations. The server typically stores the company's files.
· Launch QuickBooks on the server computer and navigate to File > Utilities.
· If "Host Multi-User Access" is available, select it. Do not use the option to Stop Hosting Multi-User Access.
