Easy Remedies for a Quick Fix of QuickBooks Error H303

Now that we've identified what's wrong, it's time to get it resolved. Here are two simple solutions to resolve Error H303:

First Solution - Turn off the host's multi-user access feature

• When QuickBooks is being used on many workstations, Error H303 frequently arises.
  
• It is recommended that just the server be configured for multiple users rather than the workstations that do not store company files.

How to Turn Off Host Multiple User Access:

1. Open QuickBooks on any workstation that has the H303 error.
   
2. Close the company files and choose "Utilities" from the "File" menu.
   
3. Even if it is an option, don't select Host Multi-User Access. Since the current workstation isn't the problem, move on to the next one.
   
4. If "Stop Hosting Multi-User Access" is an option, select it to disable the feature.
   
5. The "File" menu will appear. Select "Utilities" to access the Stop Hosting Multi-User Access option.
   
6. For each workstation that is experiencing Error H303, repeat these procedures.
   

Important Note: Since the server computer typically stores the company files, ensure all workstations have been examined before addressing it.

Setting up the Workstation for Server:

1. On the server computer, start QuickBooks.
   
2. Select "File" and then "Utilities".
   
3. Choose "Host Multi-User Access" if it's an option. When "Stop Hosting Multi-User Access" appears, avoid using it.

2. When the options display, choose Windows Firewall.
   
3. Locate and select the Advanced Settings option.
   
4. The Advanced Settings menu will appear. Right-click to open the Inbound Rules section.
   
5. Choose the "Add a new rule" option.
   
6. Click Next after selecting Port.
   
7. Select TCP and enter the unique ports that correspond to the version of QuickBooks you are using:
   

• QuickBooks Desktop 2023: 8091, XXXXX
  
• QuickBooks Desktop 2022: 8019, XXXXX
  

1. Once the port numbers have been entered, click Next to continue.
2. When prompted, Allow the connection.
