Solution to Resolve Multi-User Mode Error H303 in QuickBooks
Here are the recommended solutions you should implement to resolve error code H303 and successfully host your company file in a multi-user connection without encountering any issues.
Solution 1: Reconfigure the QuickBooks Multi-User Hosting Configuration on the Server Company File
If the company file is not set up correctly on the QuickBooks Server, the hosting may become disabled, making it difficult to retrieve the file saved on the server.
The procedures listed below can be used to examine and modify the hosting configuration:
Open QuickBooks Desktop and navigate to the File tab.
Hover the mouse pointer over the utility selection.
Select the Host Multi-User Access option.
Enable access for multiple users in QuickBooks.
Click Yes when the confirmation window appears on the screen.
Ensure that you only enable hosting for the server.
Make sure none of the workstation computers run multi-user hosting.
If you see the option to Switch to Single-User mode, QuickBooks is now operating in multi-user mode, and you must click the button to Switch to Single-User mode.
Do not change the settings if you can convert to multi-user mode.
If changing the hosting configuration does not resolve the issue, proceed to the next troubleshooting step and utilize QuickBooks Database Server Manager to address the problems.
Solution 2: Set up Windows and Third-Party Firewall if QuickBooks software is blocked
Open the Run dialogue box on the server computer and type CMD to launch the command prompt.
Obtain the server computer's IP address by typing IPConfig and pressing Enter.
Open the command prompt window on the workstation experiencing the error.
Test connectivity by entering PING followed by the server's IP address and pressing Enter.
After running the previous command, your workstation will send four data packets to the server to check if they are received.
If the server successfully receives all four data packets, it will reply with a status.
If the status indicates packet loss, you must address concerns about network settings.
